Gold Cyanidation Process - Mineral Processing Metallurgy

Aug 12, 2015  A common Cyanidation Process for Gold or called CIL and CIP. The amount of these two reagents in the slurry is very important, without enough cyanide to consume all of the valuable mineral there will be losses. Without enough lime a condition may developed that could potentially be very hazardous to the workers well-being.

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). These heaps can be hundreds of metres long and 15 to 30 metres in height.
