Real-time Plant Efficiency Measurement
200230 pages
Assessment of the measurement and control equipment available to coal preparation plants, with recommendations for plant metallurgists on which instruments to add first.
No single method gives a continuous, real time report on how a coal preparation plant is performing. Mass meters converted to yield values, on-line ash and moisture monitors, load cell chutes and automatic medium density control together supply most of what is needed. Measuring discard and slimes tonnages, particularly slimes disposal, remains the weakest point in plant accounting.

How it opens
When reference is made to the efficiency of a coal preparation plant or a specific coal processing unit, the sharpness of separation is usually inferred. The sharpness of separation reflects the ability of a unit, such as a dense-medium cyclone, to selectively separate coal and non-coal particles from each other based on the difference in their relative densities.

Improved Utilization of Underground Coal Reserves
2016
Working reference on high extraction methods, from stooping and rib pillar extraction to auger, punch, longwall and backfilling, drawn from South African colliery experience for mine planners.
What this report foundAbout 3.19 billion tons of coal now sits underground in pillars, growing by roughly 110 million tons a year under current bord and pillar practice.
R1500,00
About 3.19 billion tons of coal now sits underground in pillars, growing by roughly 110 million tons a year under current bord and pillar practice. Pillars with a safety factor of about 1.8 or higher can be extracted successfully, and 1.5 is permissible in thin seams where the pillar width to height ratio exceeds 10.
BCI Chemical Research & Analysis – ion Exchange
2012
Global, regional and South African market analysis of ion exchange resins as applied to mine waste brine, including a United States pilot plant, for technology and investment decisions.
What this report foundIon exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint.
R1500,00
Ion exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint. World demand for ion exchange resins was expected to pass 535 million dollars by 2015, driven by urbanisation, pollution and shortages of clean water in developing regions.
