Use of Ammonia Salts in Selective Copper Extraction

Use of Ammonia Salts in Selective Copper Extraction

Tailings (flotation waste) that is formed during copper production may be considered in the class of valuable wastes due to the amount of copper it contains. Owing to the decreasing grade values in copper ores, utilization of wastes such as tailings that carry certain amounts of copper as secondary sources has become a necessity in both the economic and environmental sense.Copper Slag Tailings - How to extract Iron - Mining,,21/11/2007· I have tailings that came from a copper extraction process. It is in solid 2" or less in size. We are curious if there is a way to make pig iron with this? And also how to get rid of the SiO2(silica). I'm not sure if grinding this stuff up and using some kind of mag separation process would get rid of the excess silica or not. At rough 30% its,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.
