copper copper production repositoryabout 8 % moisture. the moisture content of the concentrate is a compromise between transporting water (cost) and avoiding dust generation during transport. dewatered concentrates may heat spontaneously or even catch fire; therefore, appropriate precautions must be taken [47]. copper concentrators typically treat up to 100 t of ore per day. they are located directly at thethe beneficial effects of feeding dry copper concentratethis paper describes the benefits of drying the copper concentrate, presents different drying technologies, and demonstrates the superiority of the rotary steam dryer. advantages of using dry feed the amount of water fed to a smelting furnace can vary from 6 tons per hour, with feed rates of 600 t/h of concentrate containing 10% water.moisture effect on the combustion of a single coppermar , · · a mathematical model has been presented to study the combustion of a single copper concentrate particle with high moisture content. by using the presented model, the effect of particle moisture content on particle temperature, sulfur oxidation, and combustion heat generation has been evaluated. the mineralogical composition of the commonly used concentratecited by 4early detection of spontaneous combustionof copper [1]. the selfheating of sulfide ores in the sulphur dioxide evolved when a concentrate was heated and oxidized in air at 300°c. chen et al.
