flotation step of the Reverse Crago process. The Reverse Crago process was developed under a different FIPR in-house project. In this process, the sands are floated first with an amine plus an anionic polymer to “blind” the slime, followed by fatty acid flotation. Patrick Zhang Research Director, Mining and Beneficiation

Froth flotation has been used successfully over the last century for the beneficiation of coal and mineral particles. However, the process has been affected by certain restrictions relating to the rate at which the bubble/particle concentrate segregates from the aqueous tailings and to the recovery of ultrafine particles.

Flotation is the most widely used separation process used in the mining industry, and is regarded as the best available technology for fine coal recovery. The process also serves as the primary means of separating bitumen from silica in the oil sands industry. The process is controlled by both hydrodynamic and surface chemistry parameters.

Consequently, ash entrainment is often a problem in the flotation of South African coal, since it adversely affects the concentrate grade. It has thus been very difficult to produce a low ash metallurgical export coal by this process. This paper presents a novel method aimed at reducing entrainment, viz. reverse flotation.

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
