  • Processing complex slurries – Process productivity

    This may not carry over easily to more complex flow scenarios. Rheologically complex slurries tend to arise when solid phases are ground to finer sizes, solid fractions are increased or when gangue materials, particularly clays, are present. Falling ore grades and water scarcity are also contributors to the growing prevalence of complex suspensions.

  • The process mineralogy of gold: The classification of

    Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag ...

  • Novel approach for processing complex carbonate

    Ore in the transition zone between oxides and sulphides usually hosts both oxide and sulphide mineralisation which is extremely difficult to process by conventional flotation. These mixed ores are complex to process by flotation alone because carbonate minerals, such as dolomite and magnesite, may represent a significant proportion of the gangue.
