Cadmium Mining | Processing Equipment | Flow Chart |

Cadmium is used to make lowtemperature melting alloys, such as solder and Wood’s Metal for indoor sprinkler systems The latter is an alloy of 50%Bi, 25%Pb, 125% Sn, and 125%Cd which melts at about 160 degrees Fahrenheit, the temperature of a very hot shower Cadmium compounds are used both in black and white and color television tubesCadmium: processing Mining and beneficiation Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock The ground ore is usually treated by a differential flotation process to separate theCadmium: processingMetalpedia
