  • Mineral Ore Deposits: Meaning, Origin and Types

    Ore Deposit: Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit. It may be of any shape and form but its size is of real importance. A small patch or layer of bauxite, say one meter thick and a kilometer long will not make an ore deposit. The process of metasomatic replacement may be quite simple or

  • 11.23 Taconite Ore Processing

    Concentration is the second step in taconite ore processing. As the iron ore minerals are liberated by the crushing steps, the iron-bearing particles must be concentrated. Because only about 33 percent of the crude taconite becomes a shippable product for iron making, a large amount of gangue is generated.

  • PROCESS FOR THE CONCENTRATION OF ORES CONTAINING GOLD

    Abstract. ABSA process is described for concentrating certain low grade uranium and gold bearing ores, in which the gangue is mainly quartz. The production of the concentrate is accomplished by subjecting the crushed ore to a froth floatation process using a fatty acid as a collector in conjunction with a potassium amyl xanthate collector.
