Problems solved by technology

The flocs at the phase interface will gradually spread between the phase interfaces and occupy the entire interface area. When the flocs accumulate to a certain extent, it will seriously affect the efficiency of metal extraction and increase the time for the separation of the two phases. , increase the loss of extractant and increase the cost of production operation

Embodiment 1

[0030] Add 900 g of deionized water to the configuration slot, then sequentially added 50 g of sodium nonylbenzene sulfonate, 20 g of polyacrylate, and 90% purity of purity, at normal temperature, stirring speed 300R / min is stirred in the configuration groove. 2H, a total of 1000 g of water treatment agents were obtained. It adds to the P507 nickel cobalt separation extraction device, and the amount of dose is 10 ppm (i.e., 10,000 dose flows is 10,000), and the agent is added to the feed tube in the feed tube. The P507 nickel cobalt separation process is two-stage saponified, 11th grade extraction, six-stage substando, tertiary washing, material liquid is a metal sulfate solution such as nickel, cobalt, calcium, and magnesium, and the pharmaceutical strabraride enters the extraction level. The extracted tank is then extracted from the extraction of the 11th level. The organic phase uses sodium carbonate soap-saponation to control the pH of the extract from 4 to 5, and the saponi...

Embodiment 2

[0032]Add 940 g of deionized water to the configuration slot, then sequentially add sodium nonylbenzene sulfonate, 20 g of polyacrylate, 20 g of polyacrylate, purity 30g, at normal temperature, stirring speed 300R / min is stirred for 2 h Further, a total of 1000 g of a water treatment agent is obtained. It was added to the P204 zinc extraction device, and the dose of 20 ppm was added, and the agent was added in the feed tube in the feed tube. The P204 zinc extraction process is two-stage saponified, six-stage extraction, four-stage substance, secondary washing, zinc extraction process, and various steps. The material is a metal sulfate solution containing zinc, iron, calcium, magnesium, manganese, and the drug accumulation liquid into the extract level, and then flows out of the extract from the extraction hexa random liquid. The organic phase P204 extractant concentration is 25% volume concentration, the saponification is 65%, using ammonia water saponified, the organic flow is ...

Embodiment 3

[0034] 870 g of deionized water was added to the configuration slot, and then sodium nonylbenzene sulfonate 10g, polyteenine 30g, 80 ml of concentrated sulfuric acid, stirred at normal temperature, stirring speed 300r / min, stirred for 2 h, obtained Total water treatment agents. It adds to a Versatic 10 nickel extraction device, and the dose of 5 ppm is added, and the agent is added to the feed tube in the feed tube. The VERSATIC10 extraction process is two-stage saponified, four-stage extraction, trilaterability, secondary washing, material liquid is a synthetic sulfate solution containing nickel, cobalt, iron, calcium, and magnesium ions, and the pharmaceutical strab is entered the extraction level. The extracted box is then applied from the extraction of the fourth stage. The organic versatic 10 extractant concentration is 25% volume concentration, the degree of saponification is 60%, using ammonia water saponification, and the organic flow is 1 l / min. Substrate flow rate 3 ...

Abstract

The invention discloses a composite reagent for hydrometallurgy and a preparation method and application thereof, and relates to the technical field of hydrometallurgy industry. The composite reagent comprises the following raw materials in percentage by weight: 0.5%-5% of sodium alkyl benzene sulfonate, 2%-3% of a dispersing agent, 3%-5% of acid or alkali and the balance water, and is prepared by uniformly stirring and mixing at normal temperature. The composite reagent has a good effect of inhibiting the formation of floccules, after the reagent is added, a two-phase interface is clear, no three-phase floccules exist, the dosage of the reagent is small, impurities and floccules can be effectively removed, treatment can be carried out for about five hours, the treatment time is short, and the composite reagent is suitable for various hydrometallurgy extraction industries.

Description

Technical field [0001] The present invention relates to the field of wet metallurgy industries, and in particular, composite pharmaceuticals for wet metallurgy and preparation methods and applications thereof. Background technique [0002] Today's non-ferrous metals have become an important material foundation for determining the development of a national economic / science and technology / national defense construction. With the development of the economy, the proven high-quality minerals are close to the exhausted, which not only makes China's total supply of non-ferrous metals materials. The crisis, and because the resource is difficult to make a significant challenge, the wet metallurgical technology has a significant driving effect as a high-efficiency / low-cost / low-polluting technology in the field of extraction and purification of non-ferrous metals. The purification of the solution is a key step that the wet metallurgy process can be successful. The solvent extraction ...
