Abstract

Abstract:

The gold content of one gold mine in Gansu Province is 2.93×10-6，and gold is the main recoverable valuable element in ore.Based on the analysis of process mineralogy characteristics of the ore，the grinding fineness，collector dosage，open circuit and closed circuit tests were carried out.The results showed that the gold concentrate of 93.08×10-6，recovery of 70.93% was obtained through a closed-circuit process of one stage roughing，two stages cleaning and three stages scavenging.The test process adopted is reasonable with simple structure and medicament routine，which provide a preliminary basis for utilization and production practice of the gold mine.

Key words: gold ore, flotation, closed circuit test, grinding test, gold concentrate, exploitation and utilization of gold mine
