  • Processing Phosphates for Use in the Fertilizer Industry

    Phosphate is a key component in sustaining healthy and productive crops. While most phosphate rock goes to the production of MAP and DAP fertilizers this life-giving mineral can be made into a variety of fertilizer products and blends through the process of granulation. FEECO has been a leader in the fertilizer industry since 1951.

  • AMIT 135 Lesson 6 Grinding CircuitMining Mill Operator

    Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral

  • How aluminium is produced

    Alumina is the direct source of aluminium in the aluminium production process but in order to create the right environment for electrolysis another component is necessary and that component is cryolite. It s a rare natural fluoride mineral which due to its scarcity in natural form has been manufactured artificially.
