14.06.2018To crush the gold ore in order to obtain pure gold, the large ore of gold is fed into a jaw crusher or mobile jaw crusher for the primary crushing process. The crushing process acts as a medium of screening the fine gold ore. It is then sieved using the vibrating screen and later sent through the use of a conveyer belt.

Then, the crushed ore is mixed with caustic soda and processed in a grinding mill to produce a slurry (a watery suspension) containing very fine particles of ore. The slurry is pumped into a digester, a tank that functions like a pressure cooker. The slurry is heated to 230-520F (110-270C) under a pressure of 50 lb/in 2 (340 kPa).
