In treating copper bearing ores, materials containing primary or secondary sulfides have typically been processed using the conventional milling/flotation process which includes crushing, grinding and flotation, followed by smelting and refining of the concentrate. Copper oxide minerals are not easily floated and these ores have generally been processed hydrometallurgically by sulfuric acid leaching in slurry, vat or heap leaching processes. In recent years, bio-heap hydrometallurgical processing of secondary sulfides ores using a ferric sulfate lixiviant has gained some favor. Research has also been intense in recent years on leaching of copper sulfide concentrates, including chalcopyrite concentrates, using slurry bio-leaching, atmospheric leaching of ultra-fine ground concentrates and processes involving pressure leaching at elevated temperatures.
Pigment copper phthalocyanine does not dissolve (except by superacid protonation). Grinding it is ineffective given pi-stacking, Around a micron you are shuffling a deck of cards. A 30 wt-% solution (monomolecular dispersion) of CuPhth in Plexiglas obtains with energetic milling (attritor, zirconia). It is an awesome epsilon masterbatch dye for casting blue Plexiglas.
Weighting agents or heavyweight additives are used to increase slurry density for control of highly pressured wells. Weighting agents are normally required at densities greater than 17 lbm/gal where dispersants or silica is no longer effective. The main requirements for weighting agents are that the specific gravity is greater than the cement, the particle size distribution is consistent, they have a low water requirement, they are chemically inert in the cement slurry, and they do not interfere with logging tools.Hematite (Fe2O3). This is the most commonly used weighting agent. Hematite is a brick-red, naturally occurring mineral with a dull metallic luster. It contains approximately 70% iron. The specific gravity of hematite ranges from 4.9 to 5.3, depending on purity, and it has a Mohs hardness of approximately 6.Ilmenite (FeO TiO2). This is not as commonly used as hematite, although it has some advantages over hematite. Ilmenite is a black to dark brownish-black, naturally occurring mineral with a submetallic luster that contains approximately 37% iron. It resembles magnetite in appearance but has only a slightly magnetic character. The specific gravity ranges from 4.5 to 5, depending on the purity, and it has a Mohs hardness of 5 to 6.Hausmannite (Mn3O4). Hausmannite is being used increasingly because of its unique properties that address many of the disadvantages encountered with the other weighting agents. Hausmannite is a dark brownish-black material that is a byproduct mineral from the processing industry. The specific gravity range or Mohs hardness has not been well established. Because of its particle size and unique wetting characteristics, the material can suspended in the mix water at up to 40 wt% with a minimum of agitation, providing a liquid weighting agent. Because the average particle size of hausmannite is much smaller than that of cement, it allows the material to fit within the cement pore matrix, displacing entrained water, resulting in a lowe.
