Dense Media Separation (DMS), a preconcentration method. The Halyard team offers proven expertise in the design, engineering and operations of preconcentration methods, Dense Media Separation (DMS) (best known for the recovery of diamonds and the cleaning of coal streams).
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

The PSA separation method has become the mainstream technology for the purification of coal bed gas at small and medium scales, due to its advantages of low energy consumption, less investment equipment and high degree of automation (Arya et al., 2014; Yin et al., 2015). Its key challenge is the selection of adsorbents.
The effects of temperature, pressure, initial promoter concentration and coal seam gas/liquid ratio on the separation of methane from coal seam gas were experimentally investigated.
An efficient method to separate char and ash from oxygen carrier material is critical for the deployment of chemical looping technology. The proposed project will develop a novel method for char/ash separation from oxygen carrier that is specifically tailored to chemical looping combustion and its unique constraints and process conditions.

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
The conditions necessary for efficient, smallscale separation of coal macerals are investigated. The method developed takes advantage of known density differences of the various macerais, but unlike most separations, an isopycnic density gradient centrifugation (DGC) technique is .
