Water pollution from coal
Acid mine drainage (AMD) refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, …

spirals were introduced into the coal market. Typical throughputs of about 1.0-2.5 tph solids per start, to prove low RD capabilities, are reported in literature and audits of mines with low RD spirals have shown similar ranges. Many coal spiral plants have been designed to treat fines contributing 6-10 % of the total plant feed.

Dense Media Separation (DMS) Plants
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

This type of analysis is used when the density of separating fluids can be adjusted in a preparation plant or when different plants (with different density requirements) could be used to wash a coal. The crushed coal sample is placed in the lowest-density liquid bath. Then the sink fraction is immersed in a slightly higher-density liquid.
