Dry Processing of Coal – Progress Report: Tests Conducted on the IMS / Slater Coal Marketing Allair Dry Jig
2016
Test work on a dry jig installed at a Balmoral site, covering coal sized below 50 mm and duff below 12 mm, for producers considering waterless beneficiation.
What this report foundA 30 tonne per hour pilot Allair dry jig upgraded run of mine coal to thermal coal specification, but could not effectively beneficiate finer duff.

A 30 tonne per hour pilot Allair dry jig upgraded run of mine coal to thermal coal specification, but could not effectively beneficiate finer duff. Cut point densities and EPM values matched other dry processing equipment, though the jig appeared to give better control of the parameters governing separation. Four tests ran on run of mine coal and two on duff.
Rehabilitation of Mined Land – Soil Compaction Alleviation
2011
Final report on mined land rehabilitation trials comparing pasture species and organic amendments on compacted mine soil against normal agricultural soil, for rehabilitation and pasture planning.
What this report foundExperimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material.
R1500,00
Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.
