Processing of Copper Ore
Processing of the copper ore is realized in the enrichment plant of Fushe-Arrëz which lies north of the town of Fushe-Arrëz. At the plant are treated copper ore from two mines Munella and Lak Roshi with grade which varies from 0.9-2% Cu. Recovery in the plant is at the range 84-86% for a copper concentrate with grade 18-20% Cu.
Extraction and refining The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
