  • Processing of Nickel Laterite Ores on the Rise

    The image shown here illustrates a generalized nickel SX-EW process with heap leaching and agglomeration (click image to view larger). Recent advancements in extractants/reagents have allowed solvent extraction (SX) to significantly improve upon the separation of cobalt from nickel.

  • Bioleaching - Wikipedia

    Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, …

    The zinc blast furnace also is a sealed furnace, with a charge of sintered zinc oxide and preheated coke added through a sealed charging bell. The furnace is rectangular, with a shorter shaft than the iron blast furnace. A blast of hot air through the tuyeres provides oxygen to burn the coke for heat and to supply carbon monoxide reducing gas.

  • Mineral processing | metallurgy | Britannica

    Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
