What is mineral liberation and how does it affect optical sorting
Mineral liberation is the process of lowering particle size from large to small. Because mined ore often contains both valuable minerals and gangue, effective recovery of the valuable minerals necessitates crushing the raw ore to a specific size, allowing for their separation from the gangue. The ex...

$What are the three major categories of refractory gold ores?$

What are the three major categories of refractory gold ores?
The first type: high arsenic, carbon, and sulfur type gold ore. This type contains more than 3% arsenic, 1-2% carbon, and 5-6% sulfur. Using conventional cyanide gold extraction technology, the gold leaching rate is generally 20-50% and requires a large amount of Na2CN. Although a higher gold concen...
