1.1 phases of a mining project home elawmetals (such as cadmium, lead, and arsenic). the beneficiation process generates highvolume waste called tailings, the residue of an ore that remains after it has been milled and the desired metals have been extracted (e.g., with cyanide (g) or sulfuric acid (copper)). if a mining project involves the extraction of a fewthe 10 biggest silver mines in the worldnov , · commercial production started in 97. cannington also produces lead and zinc. the sulphide ore extracted from the underground mine is sent to the nearby beneficiation processing facility where silver, lead and zinc concentrates are extracted. the mine produced 3,400t of lead and 56,300t of zinc in the ended june .energy use in metal production publicationsthe degree of beneficiation required, particularly grinding to achieve liberation since this is the most energy intensive operation in beneficiation; and the overall recovery, since losses along the valueadding chain require more ore to be mined per unit of metal produced. figure 1
