Wastes disposal

Processing of waste from man-made deposits is an urgent and complex task. Very often these wastes are wastes of the main production, because it’s impossible to carry out the enrichment of products of a certain size with existing technical means. In different industries, these sizes may vary: for non-metallic rocks - this is waste with a particle size of less than 5 mm, for coal slimes - less than 3 mm, for gold- bearing ore - hundreds of microns.

Our equipment provides screening of such materials into fine grades

Process wastes

Processing of waste from man-made deposits is an urgent and complex task. Very often these wastes are wastes of the main production, because it’s impossible to carry out the enrichment of products of a certain size with existing technical means. In different industries, these sizes may vary: for non-metallic rocks - this is waste with a particle size of less than 5 mm, for coal slimes - less than 3 mm, for gold-bearing ore - hundreds of microns.

Our equipment provides screening of such materials into fine grades.

Process wastes: e.g. Zinc concentrate

Purpose:

screening pulp of basic sulfates of non-ferrous metals in order to purify zinc sulfate from the gypsum component with a fineness of +0.04 mm.

Application:

mining and processing plants of non-ferrous metallurgy.

KROOSH Results:

the zinc content in the concentrate after removing the gypsum component from the original product reaches 45-47% against 25% in the original product, with the almost absence of gypsum in the zinc concentrate.

Reason of installation:

the customer couldn’t receive on-spec good product with the conventional screeners.

Product:

processed waste from electric steelmaking: separation of gypsum from zinc concentrate 0-0.04mm

Coal: desliming

Coal: Desliming 0.1mm

Purpose:

to increase efficiency of the line by removal of fines >0.1mm with the high ash content 50-60%.

Application:

slime storages of coal-washing plants.

KROOSH Results:

removal of fines >0.1mm with the high ash content (50-60%) allowed to receive the extra production volume of coal with low ash content 9-10%.

Reason of installation:

other screeners couldn't screen this product.

Product:

coal + 0.1mm to -3.0 mm for coke and by-product process.
