The dewatering of copper, lead and zinc concentrates used Xinhai efficient deep cone thickener ceramic filter. The concentrate moisture was about 12 after dewatering. Process Indicator Copper concentrate grade40 Copper recovery rate83.45 Lead concentrate grade50.13 Zinc concentrate grade84.68.
Jan 17, 2018 Most copper dressing plants are always nagged by the low copper recovery rate. In the usual mineral processing plant, the recovery rate and quality cannot be satisfied at the same time. Throughout the concentrators operations, some copper impurities cannot be completely removed, nor can they be completely dissociated.

The silver ore flotation production line is mainly composed of ball mill, flotation machine, leaching tank, zinc powder replacement device, two-layer three-layer washing and thickening machine, etc. The production line has the advantages of high efficiency, low energy, high
The energy efficiency resulting from the use of copper in high efficiency motors, electrical transformers, underground power lines, air conditioning and refrigeration equipment, electric vehicles, etc. has a significant impact on the release of green house gases resulting from the generation and use of fossil fuel based electrical power.
Screen printing is the leading electrode deposition technology in PV mass production due to its simplicity and high output. However, the resistivity of low-temperature silver paste is higher, resulting in increased contact resistance and finger-width-caused shading loss, which limit the cell performance .The copper plating is a competitive alternative.
