Key-words: Electrorefine, anode slime, copper. Abstract Copper sulphides Concentrates, from the flotation process of copper primary ore; contain, commonly, small amounts of precious metals, such as gold and silver. During the smelting process of those concentrate all gold and silver are practically in the blister copper, which is cast into anodes.

The silver ore flotation process has five operation stages XinHai Views (254) ... The first washing liquid is replaced with zinc powder to obtain gold and silver slime → pickling and drying → smelting gold and silver alloy and casting it into anode plate → electrolytic refining to separate gold and silver.
Florrea has a wide range of collectors that provide varing levels of power and selectivity for both sulfide and industrial mineral applications. Each of the following basic product familles have a variety of derivatives to accommodate the needs of each particular ore. In most cases, our custom formulations of these basic chemistries are developed to meet the industrial needs of the mill.
Porphyry copper ore deposits belong to the main sources of copper, molybdenum, as well as gold, silver and a number of concomitant elements – such as rare, precious and trace elements. Countries with developed copper industries (and Uzbekistan is one of them) are working on establishing major processing sites, which are to process huge amounts of porphyry copper …
