Most mills keep detailed accounts of operating and maintenance costs, broken down into various sub-division, such as labor, supplies, energy, etc. for the various areas of the plant.
copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and there is no critical temperature at which this crystal structure changes.
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
