Here are the main steps in processing diamond ore. A number of these processes use equipment from Multotec: 1- Crushing The first step in kimberlite ore processing is crushing. This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps.
Coal gasification fine slag is a kind of solid waste with low resource utilization rate. The complex embedding of residual carbon and inorganic minerals (ash materials) is the main reason restricting the efficient resource separation and utilization of residual carbon or ash materials. Hydrophobic–hydrophilic separation (HHS) is a separation technology in which …
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Figure 11.1: Principle of dense medium separation. Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end-product, clean ...
Dense Media Separation is a well-known sink-float method and technology used within the coal, iron ore and diamond industries. In the process of Dense Media Separation in diamonds, a powdered ferrosilicon (which is an alloy of iron) is suspended in water to form a very defined pulp density (heavy liquid), close to the density of diamond (3.52 g ...
Description. Dense media separation (DMS for short) is a widely used in the mining industry by densitometry errand valuable minerals and non-valuable rock separation process. The process can be conducted at particle sizes as coarse as 300 mm and as fine as 500 μm with high separation efficiency, depending on the liberation characteristics of ...
Mar 01 2008 0183 32 No actually diamonds is the first process and after millions of years of being expose to h2o from the surface they convert in to coal i believe I know that they have the same atom structure but the atom structures in diamonds are more closely together and after time they spread apart creating coal...
When coal is mined, miners go right to the source where the coal is formed. Diamonds, on the other hand, are brought close enough to the surface to be mined by volcanic eruptions. In addition, the carbon that forms diamonds is …

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
39.3.3 Heavy media separation. Heavy media separation dates back to several centuries. Initially, a fine magnetite was used as a heavy media. In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore. The heavy media process is usually used for treatment of coarse coal above 9.5 mm in size.
