Benefits of technology

The present invention is about a reusable ear system for copper anodes that can be used to carry them between smelting and electrorefining processes. This system prevents smelting the anodes' ears on the same ones, which improves the process and reduces waste. The system is designed to automate stages without needing manual intervention, making it safer and more productive than previous methods. Once assembled, it can be used in the same way as current anode copper.

Problems solved by technology

Currently the anode copper molded by means of molding wheels has a great variability with respect to the geometrical dimensions, the aforementioned is mainly produced by a poor leveling of the molds or due to other factors of the molding process and this leads to the existence of a percentage of rejected anodes which do not comply with the allowed dimensions in the cell with the subsequent reprocessing of the defective anodes, thereby having an effect on the costs, this phenomenon becomes more critical when using technologies working with high current densities.

first embodiment

[0051]In a first embodiment, the hanger means (10) comprises a reusable central bar (11) to be located on the upper edge of the enhanced geometry anode (22). On the ends of the reusable central bar (11) emerge reusable ears (12) having engagement means (13) which take the enhanced geometry anode (22) on its upper corners.

[0052]The enhanced geometry anode (22) is formed in the mold (7) as shown in FIGS. 13 and 14. In this case, the central rectangular-shaped cavity (8) receives the liquid copper forming the enhanced geometry anode plate (22). On the upper part of said mold (7) and towards the corners of the central cavity (8) are located two small recesses (14) to receive the liquid copper forming two small upper projections (15) which replace the ears (2) of the previous art.

[0053]These small upper projections (15) are used by the engagement means (13) to fasten the hanger means (10) to the enhanced geometry anode (22).

second embodiment

[0054]In the. present invention, the hanger means (10) comprises a reusable independent central bar (16). On the ends of this reusable independent central bar (16), are fitted two reusable independent ears (17) which have fastening means (18) formed by a lower notch (23) on which is housed the small upper projection (15) of the enhanced geometry anode (22).

[0055]The reusable independent ears (17) have on the opposite side to the fastening means (18), an overhanging short bar (19) with a male rim (21). This male rim (21) is fitted with a female slot (20) located on the reusable independent central bar (16). This allows to generate a fastening mechanism between said reusable independent central bar (16) and said reusable independent ears (17) thus achieving a system which can be easily dismountable and mountable to be compacted during its transport.

[0056]In FIGS. 19 to 22 is shown the assembly of this second embodiment of the present invention. The reusable independent central bar (16...

Abstract

The present invention relates to a system consisting of an anode hanger means (10) and an enhanced geometry anode (22) which makes possible to reuse said anode hanger means (10) minimizing the production of scrap, allowing an enhancement of the process between the smelting and the electrorefining wherein said hanger means (10) is formed by a reusable central bar (11) to be located on the upper edge of the enhanced geometry anode (22) wherein said reusable central bar (11) has on its ends reusable ears (12) having engagement means (13) which take the enhanced geometry anode (22) on its upper corners and wherein in the upper corners of said enhanced geometry anode (22) emerge two small upper projections (15). The small upper projections (15) are fitted with said engagement means (13) to secure the hanger means (10) to the enhanced geometry anode (22). Alternatively, the hanger means (10) comprises a reusable independent central bar (16) wherein on the ends of said reusable independent central bar (16), are fitted two reusable independent ears (17) which have fastening means (18) formed by a lower notch (23) on which the small upper projection (15) of the enhanced geometry anode (22) is housed.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a system comprising reusable ears for copper anodes used in the electrorefining process, which replaces the need of having these same anodes formed by its own ears. These ears currently only serve for the electrical contact function and work as a current anode supporter, and, therefore, when finishing the electrowinning process on the cathodes. this material is left intact and must be re-smelted again to form a new anode. This invention makes possible to use an anode without ears which allows to minimize the scrap production together with its consequent associated costs,BACKGROUND OF THE INVENTION[0002]The high-purity copper production process involves several stages starting with the reception and sampling of copper concentrates. It is important to perform a sampling of them as well as classify them according to the copper, iron, sulfur, silica concentrations and impurities such as mainly arsenic, antimony and z...
