8 Types of Gold Ore- Properties and Ways to Process

2021-11-30  8 Types of Gold Ore- Properties and Ways to Process. Gold mainly appears in the form of natural gold and minerals in the ore such as pyrite, tellurium ore, sphalerite, and gold in gangue, etc. About 70% to 75% of the gold in the deposit is in the form of natural gold, while the other 20% occurs in the form of telluride. The remaining 5% to 10% ...

Improved recovery of a low-grade refractory gold ore

2014-7-1  In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.
