The crystals are shoveled with copper shovels into this hopper, which fills the pushcar underneath through a spout with slide in the center. As the tanks are 6 ft. deep, the crystals have to be thrown at least 7 ft. high, and in doing this work some of the crystals unavoidably fall back into the tank, frequently striking the shoveler.

Niextraction in the PGM industry is performed both under atmospheric and pressure leach conditions, typically using anolyte/spent electrolyte of 70–100 g/L H 2 SO 4 which is higher than traditional Ni matte leaching in the absence of PGM's.

Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
There the sulphide minerals are partially oxidized and melted to yield a layer of matte, a mixed copperiron ... and copper extraction and other base metals from ...
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Matteis a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper,nickel, and other base metals.
Copper heap leach operations are much smaller than copper dump leaches. On the average, heaps contain between 100,000 and 500,000 metric tons of ore. Solvent extraction. Once the PLS is collected it is sent to a solvent extraction (SX) plant to remove the copper.

Solvent extraction begins with an organic solvent, which separates copper from impurities and unwanted material. Next, sulfuric acid is added to strip the copper from the organic solvent, producing an electrolytic solution.
