Process for treating acid baths containing metallic substances.

Description

DESCRIPTIONS. This invention relates to a process for the treatment of acid baths containing metallic substances. In particular, in a nutshell, a process of the shape of the prosant innanotone can be used for the recovery of several metallic substances such as, for example, femin or zinc, contained in metal anthems which can be used to form hollow gold objects. The production of hollow magnets in gold, especially platinum generally involves assortment (a lance of metal attached to a resistant plate in a precious metal, or “screw”, which is easily formed. of metal in the absence of the ccnr^tio results in η^ίη^'π-ιο constituting the soul. without help to press the ecrsonipi on the external metal, but to take a bath of citric acid diluted in water, in the same veolopo immersed in water. copper, a lot of copper, a certain amount of residues of utric acid is a harmful substance that causes opucrates and constitutes the effects of specific plants. Innocently put yes |.Reroethane in the gold renucoid from the ninteoninine compounds is immersed in a base of nitric acid (HNOS) or hydrochloric acid (IICI). The original purpose of the second invention was to overcome the innocent prenets. To this result, in the invention of the proposed invention, the idea of ​​conducting a test with the characteristics indicated in reference 1. The characteristics of the present invention are dependent on the origin. This helps to prevent acid baths from containing harmful substances which can be used to the advantage of substances, such as carbonate of carbonate which has been processed more than the moles and substances that have been obtained from the materials intended for these purposes. rifioa t <tntribuendo in tal modo ad un imoingo dnlle risoste in linec con lo attnali nnidenoe di natura ambientale.

These and further advantages and characteristics of the present invention will be better understood by a person skilled in the art from the following description and the accompanying drawings, given by way of example but not to be considered as limiting, in which: - Fig.1 is a simplified biochemical diagram representing the elimination phase of neutralization of the acid bath (e.g., the protective coating) in accordance with the present invention; - Fig.2 is a simplified bioecho model which represents a possible electrochemical recovery project from the microbial cell of the pre-series but with the addition of the actual recovery of the bath; - Fig.3 is a block-shaped figure and represents a further embodiment of the present invention; - Fig.4 is a bio-based sample which represents a possible recovery of chemical residues from the wastewater treatment plant. This section also includes those found in the exhausted acid gel. A similar process involves a cleaning treatment with calcium carbonate (CaCCh) of exhausted baths containing metallic substrates. Generally speaking, the exhausted acid bath is an acid bath of nitric acid that is suitable for use in one or more colors of crystalline metallic objects on the same surface. corrosive caeudtd in the csnPrepare incidence Cd. The typical precursors of magnetic fields with internal non-gold metal, such as copper initially, are known to be the steps of the non-gold metal that have been removed from the fields or concentrated. preliminarily determines the conditions of fermentation of the acid bagoo. For example, a caitogram of electron attack at a concentration of 36 degrees Baumé is the amount of solubility of 20 / 100 grams of copper.

For example, we will look for a bath of spent nitric acid and then immerse it in water. We will also look for objects with an internal copper core. In this case, the copper will be present in the bath in the form of copper nitrate (Cu(N03)2) or in the form of copper nitrite (CuNChX). The imrisk (tei carionoto of oaisio determines a phase of neutralization of the ricido lake with pH taralsemento. In practice, calcium is absorbed into the exhausted calcium, but the dissolved calcium acts as a catalyst in the cavities of the salt bath. Therefore, a non-volatile calcium nitrate (CaCl2) solution is obtained, which results in the formation of calcium carbonate and the formation of water: CaC Oifl^XO 3=Ca( 03)2+IW+mO 2.

At the same time, the surface carbonate of ceteium can be found in the same way, but it appears in the Cu-Zn fields commonly referred to as “tombak” and “tombaccn” because the zeta ion scale in the animal body does not exist. In the fourth step, the oxide cage will be present targeted with Zn(N03)2 oxide nitrate oxide (n(NChX Anoraa, and a bathroom that is subjected to cleaning with a carriageway, or other meals outside the tomb, such as N^cSial, CoOmio or Petteoto. For example, the bath of the etollstsi may be constituted by a dildo or dildo equipment used to remove the mixtures from the components or epochs of the horn or printed circuits. unresolved complaints can cause wax that has not been subjected to treatments or recrystallization of differentiated cells to produce two successful processes. (BAS is placed in a neutralization tank (VN) in which the calcium eaborator (CA) is used for neutralization. in the case of the present description. The following doctrine gives examples of the processes of reconciliation of the neutralized death, identified as “Process 1” and respectively “Process 2”. The material is placed in a vacuum chamber (2) containing calcium carbonate (3), preferably supplied by waste or by-products of marble processing, gravel or shells of molluscs and, more generally, supplied by material from the earth containing carbonate. The calcium carbonate is used to separate the waste. The materials of the marble are not treated with calcium carbonate and contain calcium carbonate in order to improve the process. For example, marble is a cardboard containing calcium carbonate in a quantity greater than 50% in weight. Ceicarean crushed stone contains onofticza earbanate eli aelcin in quantities lower than 50% by weight, the grains of the mills contain calcium carbonate in quantities greater than 90% by weight. The resistance of celcium carbonate to the electrolysis phase is important due to the presence of oxygen through the pH of the bath. The type of electrode is a ¼" anode (4t is a hot electrode, made of titanium oxide, ¼" cathode (5t is an electrode made of a flat sheet of metal). At the electrodes a voltage (with a voltage) is applied, and a constant pre-established at 3 V is applied. At the base of the electrode there is a rare earth of oxygen present at the anode and the methyl cadmium (zinc, oxide, cadmium or platinum), that is, the ions present in the bath are neutralized on the cathode. Calcium carbonate is present in the vat and the electrolysis favors the progressive absorption of copper (I) with the addition of copper (ριιό6ο0) in the exhausted bath (neutralize) on the catalytic reaction with the acidic slag. In this way, in the case of waste materials or considerable waste, copper οΡιΖΕο^^ and targeted celsium (Oa(N03)2) were obtained in eclda ¢1 which is generally between 3.5e OO). They are (also called nitrogen, cadmium or zinc, or electrolytic acid, electrolytic acid or electrolytic zinc.) The purpose of this is to use it as a fertilizer in agriculture. The most common and most common mechanisms are Cepositano me cathode, which are used industrially. In the diagram of F().d the reference “6” represents the ^1^10^ of dicalcium nitrate extracted from the bath (2). It is also possible to use calcium-targeted notions in an opposing crystal to obtain the correct association of calcium ions if desired. Experimental tests conducted by mixing acid-treated baths containing copper have shown that during the electrolysis process, the bath becomes chromated, with a fluorescent color, resulting in a substantially uniform bath. This is due to the fact that the copper dissolved in the bath is deposited on the cathode without returning to solution because the bath is buffered by the alumina carbonate added to the bath before the electrolysis process begins. The zirconium ions are continuously dissolved in the vast electrolyte, using a zirconium ion (not shown in the drawings shown) to promote the release, from the zirconium ion, of the zirconium ions that are formed in the calcium deposition system previously. In other cases, the zirconium ions are continuously dissolved in the materials introduced (see figure 1). Lz seessz eennmenoZogia is used, more generally, for acid baths and zomtenenti zllri m^taid.

For example, if copper in the form of copper nitrateCu(N03)2 is present in the exhausted neutralized bath, the following reactions may develop: Cu(NO 3)2 2KOH·)Τι(OH)2+2KNO 3′Calore Cu(NO3)2 +2KOH=>CuO+2KNO3+H2N + CaSore In part, an exothermic seawater develops which brings the temperature of the bath to about 80°C. Preference should be given to avoiding that the temperature of the bath exceeds a certain limit which may determine the release of gases dangerous to the human body such as hydrogen peroxide. The release of KOH is slowly achieved. Presumably, the temperature of the saturated KOH solution is such that the release of the KOH does not exceed 90°C. iZTaS case in ami 1s temperature of the supernatant bath is 90°C, the NOH injection will be interrupted until the bath temperature returns to 80°C.

The processes described above, namely: electrolytic metal recovery and chemical recovery using potassium slag, involve a neutralization phase of the waste product and consist of the addition of potassium slag carbonate, which allows the production of cultivation fertilizers that also contain the residue, in addition to the elimination of the acids contained in the exhausted waste product.Painful observation by caecect cppore shows that a process in accordance with the present invention is a process used for the preparation of an exhausted acidic solution containing selective and / or incidentally recoverable ions. The chemical or electrochemical properties of metallic ions are required to be known. The reception of the metals is preceded by a type of neutralized neutralized neutralized continental neutralizing medium. heat source and neutralization source (VN) in the calcium cathode.
