A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling Copper
In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011). In 2010, 770,000 metric tons of copper were recycled, at an estimated value of nearly six billion dollars...

Jaw crushers are used as the primary crushers in the first stage of a crushing process for the breaking of large-sized rocks, while jaw crushers with smaller mouth openings are used to break smaller ores into finer sizes. Two basic jaw crushers types are produced, being single or double-supported, depending on the movement system of the jaw.احصل على السعر
