Gold Flotation Production Line

Solution Introduction

Flotation is widely used in gold Processing. In China 80 rock gold is Processed by flotation. Flotation Process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost.

Solution Appliion

Gold Flotation Process is use to Process fine gold sulfide gold-containing quartz ore multi metal gold-containing sulfide ore and carbon-containing ore.

Solution Description

Gold Flotation Process FlowGold mineral flotation normally adopts one stage grinding-flotation Process but stages grinding and flotation for ore with uneven distribution.

Grinding fineness of goldFor the gold wrapped in sulfide minerals sulfide ore reaches monomer dissociation but for the gold with gangue grinding fineness should reach gold monomer dissociation. Grinding fineness of minerals is determined by test.

Concentration of gold flotation ProcessFlotation for large density and coarse particle needs thick pulp whereas for small density and fine particle need dilute pulp.

Other Process conditionsIn addition to the grinding fineness Process conditions of gold flotation also includes slurry concentration reagent dosage aeration quantity flotation time.

Solution Case

A gold mine in Yunan capacity was 300t/d the main mineral was pyrite fine granularity of gold the gold had close relationship with metal sulfide mineral. This plant adopted the flotation Process---one roughing two cleaning and two scavenging. But due to surface oxidation of arsenic antimony mineral it adsorbed amount of flotation reagents and the flotation effect was poor. So the plant authorized Xinhai to reform the Process. Xinhai replaced cyclone tailings with stages grinding and flotation and flotation tailings in accordance with existing problems in production and Xinhai also changed the number of machine and reagents rules. Finally this plant obtained excellent indexes. The indexes comparison as follow

The production Process flow into stage flotation flowsheet easy operation to achieve early harvest fast charge minerals useful higher impurity minerals adjust the structure of flotation machine improve the separation environment but also improve the flotation pulp mineralization effect the index of stability and flow.
