  • The process design of gold leaching and carbon in pulp

    The CIL process The carbon in leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and

  • A Review on Novel Techniques for Chalcopyrite Ore Processing

    Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

    Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms).In humans, copper is essential to the proper functioning of organs and metabolic processes. The human body has complex homeostatic mechanisms which attempt to ensure a constant supply of available copper, while eliminating excess copper whenever this occurs.

  • Eutrophication

    Eutrophication (from Greek eutrophos, quot;well nourishedquot;), or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. This process may result in oxygen depletion of the water body. One example is the quot;bloomquot; or great increase of phytoplankton in a water body as a response to increased levels of nutrients.
