Six Australian coals were selected to determine their potential to produce, ultra low ash (less than 2 per cent) coal by progressive size reduction followed by density separation and/or froth flotation. Density separation in organic liquids is effective in the absence of contaminating liberated mineral matter which can be removed by froth flotation with several cleaning stages. The limit of cleaning of these coals was an ash value of 1 per cent while commercially attractive yields were obtained at 2 - 3 per cent ash depending on the coal.

A by-product of the lead smelting operations at BHAS is a copper-lead matte typically containing 35% copper, 38% lead and 12% sulphur. A hydrometallurgical treatment process has been developed for the treatment of this matte to recover copper as cathode and results in a lead-sulphur residue which is recycled to the lead smelter. A commercial plant with a nominal capacity of 4000 tpa utilising this process was commissioned during 1984. This plant has been shown to be capable of producing copper cathode at rates approaching 4000 tpa over short periods of time.

One-third of the world's and most US kaolin is produced from Late Cretaceous and Early Tertiary sedimentary strata in Georgia and South Carolina. The kaolin is part of a belt extending to Arkansas of aluminous lateritic deposits, including bauxite. Original sediments were profoundly altered by chemical weathering during Early Tertiary time. Mining exploits those uncommon deposits where extreme leaching and chemical recombination have produced a clay of nearly pure mineral kaolinite. Properly selected and refined, kaolin is an important pigment, filler, extender and chemical compound in the paper, paint, plastics, ceramics and catalyst industries.

It is generally held that cone crusher application technology is strictly an art and thus subject to the vagaries of emphirical and/or trial and error judgments. While this is basically true, certain factors have been identified which, when properly defined, can significantly reduce the element of chance. This paper will bring out these factors as well as pointing out other technologies available to predict and/or analyze cone crusher performance.
