Used Mining Equipment

PRIMARY MILLS (3) 10ftX8ft The objective in primary grinding is to liberate the minerals by grinding the ore into fine powder. When the ore has been ground fine enough it flows to the lead roughers while the ore which is still too coarse is recycled to the ball mills for more grinding. 2,200 tons per day of ore is ground in three 10 foot diameter by 8 foot long ball mills operating in parallel ...

Cyanide Use in Gold Mining - Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
