CN104294057A - Method for extracting gold from copper ...

The invention discloses a method for extracting gold from copper-oxide oxidized gold ores. The method comprises the following steps: 1, carrying out ammonia-cyanide leaching on the copper-oxide oxidized gold ores to obtain an ore pulp; 2, adding hypochlorite into the ore pulp, and stirring to remove copper in order to obtain a copper removed ore pulp; 3, carrying out

Gold Extraction from Different Types of Ore

10.01.2020  Polymetallic sulfide gold ores containing lead, zinc, and copper refer to ores that coexist with gold ores and considerable amounts of copper, lead, zinc, and other sulfur ores. The secondary ore has many components that can be extracted. Gold is present in different particles, which is unevenly distributed. Flotation gold extraction process is mostly used for

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
