The fine sulfide ore is going to froth flotation machine for recovery of copper. It does this by adding a chemical reagent to the solvent extraction tanks which selectively binds with and extracts the copper, is easily separated from the copper (stripped), recovering as much of the reagent as possible for re-use. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction. The solvent extraction process concentrates and purifies the copper leach solution so the copper can be recovered at a high electrical current efficiency by the electro winning cells. The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. The concentrated copper solution is dissolved in sulfuric acid and sent to the electrolytic cells for recovery as copper plates.

One unit of Zenith Company aggregate production line can produce up to 800-1000 TPH, the grain size will be 0-5mm, 5-10 mm, 10-20mm, 20-40mm, 40-60mm and even larger.Zenith Company is a premier supplier of crushing and screening equipment, and related auxiliary equipment in China. We provide complete crushers and screen machines for producing all types of aggregate for our Egypt clients and customers all over the world.

Each line consisted fo a rod mill in open grinding circuit, followed by a primary ball mill in closed circuit with 508mm hydrocyclones and a secondary ball mill also in closed circuit. All ball mills were identical. the flotation feed size produced from this circuit is about 150microns.After priamry crushing, the crushed copper ore will be delivered by conveyor system into a fine ore bin, from where it fed two identical line of grinding.

Calcite powder has wide applications.Calcite is a kind of calcium carbonate mineral with wide spread. It is generally used as filler in many industries, such as artificial floor tile, rubber, plastic, paper making, paint, oil ink, construction material, textile etc. To get these uses of calcite powder, we need to grind the raw calcite into powder. There are many countries in the world that have calcite mines, among which, China, Mexico, UK, France, America and Germany are the representative countries. While being used as filler, calcite powder can increase the volume of products, reducing the production cost. The Mohs’ hardness of calcite is 3.

The inclination of the large axis of the elliptical motion relative to the screen surface is controlled by the inclination of the rotary eccentric vibrators away from the intended direction of travel of the material on the screen surface.In achieving the foregoing motion, two rotary eccentric vibrators may be arranged on a screening structure with the axes of the vibrators inclined from the vertical to a similar degree away from the intended direction of travel of material to be conveyed across the screening surface and inclined from the vertical oppositely in a plane perpendicular to the intended direction of travel of the material. The inclination of the vibrators in a plane perpendicular to the intended direction of material travel varies the width of the ellipse.

sludges, equivalent to 0.F.85 C/Fe2O3.By taking in consideration all the aspects associated with the reduction process, such as residual C, reduction yield, metallization ratio, and slag characteristics, the best mix to have a good compromise between reduction yield and metallization degree is a 1:1 red mud/B.
