Condor Dense Medium Separators Sepro Mineral

Condor Dense Medium Separators | Sepro Mineral

Condor Dense Medium Separators provide a simple, cost-efficient way to separate and recover valuable minerals at a coarse particle size, ranging from as fine as 0.5 mm to as coarse as 50-70 mm but typically in the range of 150 mm. Dense medium separation technology is used for a wide range of mineral separations to produce premium concentrate.

Separation Density an overview | ScienceDirect Topics

In the US and Australia, dense medium separation accounted for over half of the preparation done in 2001, as shown in Table 1.8 (Cleaner Coal Technology Program, 2001). In South Africa, dense medium separation accounted for 85% of the coal preparation, due to the very high levels of near-gravity material present in coal mined in this region....

"ULTRA CLEAN COAL PRODUCTION USING DENSE

"ULTRA CLEAN COAL PRODUCTION USING DENSE

The production of high quality silicon requires the use of ultraclean coal containing less than 1.5% ash. The magnetite used to clean the coal in a dense medium process is a contaminant that seriously impacts the quality of the final silicon product. As such, research has been conducted to evaluate the potential to substitute the magnetite with fine silicabased alternative material

AMIT 145: Lesson 3 Dense Medium Separation

For example, a 400 tph feed to a dense medium process equates to a volumetric flow rate of 1000 gallons/min or 3.785 m 3 /min. At a 4:1 medium-to-coal ratio, the volume of medium is 15.14 m 3 /min. To achieve a m = 1.50 RD, the required amount of magnetite in the medium is 704 kg per m 3 of medium or 10664 kg/min = 10.7 tonnes/min. Magnetite

The Effect of Dense Medium Viscosity on Separation

The Effect of Dense Medium Viscosity on Separation

1990-8-9 · This paper reviews the literature on the influence of viscosity on separation in dense medium processes, for both baths and cyclones, in the context of the well-known fundamentals of particle motion in fluids. It is concluded that viscosity does play a role in determining both the separation density and the extent of separation inefficiency (Ep). because most DMS processes probably operate in
