  • CIL Gold Mining Solution Mineral Processing

    Carbon in Leach (CIL) process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon.gold processing Mining and concentrating Britannica,The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
