A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge, by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge.
Vacuum flotation In vacuum flotation the process stream is saturated with air at atmospheric pressure and introduced to the flotation tank on which a vacuum is applied giving rise to the generation of the air bubbles. The process can be run only as a batch process and requires sophisticated equipment to produce and maintain the vacuum.
Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

Flotation – Sulfides . Copper and moly are often found together as sulfides*†. Sulfides in solution will float or sink with the right combination of chemicals and gas bubbles (froth flotation). These sulfide ores are separated from gangue (waste) material, then from each other, by froth flotation. Copper /Molybdenum Flotation Circuit Steps:
2. The concentration operation is mainly to improve the ore concentrate grade. The flotation layer should be thin so that separates the gangue. It is not appropriate to use a flotation machine with a large aeration volume. Therefore, there are differences between the froth flotation machine of concentration, roughing and scavenging. 3.
The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a …

Rotary vacuum disc filters have become increasingly popular for taking coal froth concentrates passed directly to the filter thereby eliminating the use of a thickener. To accomplish this, emergency overflows are provided on the filter tanks and if the froth feed overflows, the overflow material must be pumped back to the froth flotation cells.

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself ...

Hyperbaric disc filter dewatering of coal flotation concentrates is common place in China, Eastern Europe and Russia. The hyperbaric disc filter uses an air pressure of up to 0.6 MPa, to drive the dewatering process. This additional pressure is able to achieve surface moisture levels significantly less than conventional vacuum filtration.
Horizontal vacuum belt filters are a common dewatering technique for fine coal applications in Australian coal mines. Through the use of these filters, material as coarse as spiral product or as fine as froth flotation concentrates can be dewatered effectively. Horizontal vacuum belt filters work by applying vacuum below a filter media. As the name
