Copper extraction by wet chemical method

2018-1-1  The results show that copper content ranges between 1 and 9% which is better content than some of the exploited ores found elsewhere. One example is from the Democratic Republic of Congo where ores grade between 2.68 and 2.96% (Yager, 2016).In Chile copper deposits range between 0.4 and 1.0% (Kuck, 2014 (pp. 108–109)) while in South Africa copper deposits grades are between 0.49

Iron Ore Processing Gold,Copper,Graphite,Quartz

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
