Plant operations may be either batch, semicontinuous, or fully continuous to produce blister copper or other end product.Environmental Impacts of EnergyEfficient Pyrometallurgical ,Cu production are the mining phase, concentrate processing (percent sulfur and iron), the smelting technology, the degree of oxygen enrichment in the process, and the generation and use of process heat. The consumption of energy in European pyrometallurgical Cu production is relatively low compared to other regions (Fthenakis et al. 2009).
After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical. Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation. The obtained copper concentrates contain on average 30 percent copper, but grades can range from 20 40 percent (ICSGSimplified flowsheet of pyrometallurgical process for copper,Some of the pyrometallurgical and hydrometallurgical processes to consider are physical separation, magnetic separation, flotation, leaching, and direct reduction roasting of iron (DRI).
