CASE

Namibia 1,100t/d Copper-Lead Mineral Processing Plant

The metal minerals in the ore were mainly iron oxides, including hematite, magnetite, limonite, covellite, chalcocite, etc., most of which were oxidized. Gangue minerals were mainly composed of quartz, calcite, chlorite, and clay minerals.

Xinhai Solution

01

The grade of copper in the raw ore is 1.26%, and the oxidation rate of copper was 65.87%. Gold, lead, zinc, silver, sulfur, iron, and other elements were of low grade and have no recycling value. Xinhai had designed two roughing, two scavengings, and three concentration flotation processes.

Main Equipment

Energy Saving Ball Mill

Energy Saving Ball Mill

Energy-saving ball mill is a high efficient and energy-saving ball mill with rolling bearing.

XCF air inflation flotation cell

XCF Air Inflation Flotation Cell

An air inflation mechanical agitation flotation cell with slurry suction（as suction cell of KYF flotation cell).

KYF Air Inflation Flotation Cell

KYF Air Inflation Flotation Cell

An air-inflation mechanical agitation flotation cell without slurry suction (This type of cell is designed referring to Finland Autoquenpu OK flotation cell).

Efficient Improved Thickener

Efficient Improved Thickener

A new efficient thickening equipment independently developed by Xinhai.

Project Result

After two roughing, two scavengings, and three concentration flotation processes, 90% of raw ore with a grinding particle size of -200 mesh and can be selected as a concentrate with a yield of 4.70%, a copper grade of 19.12%, and a copper recovery rate of 71.28%.
