Micro concentrator photovoltaics (micro-CPV) is an unconventional approach for developing high-efficiency low-cost PV systems. The micrifying of cells and optics brings about an increase of efficiency with respect to classical CPV, at the expense of some fundamental challenges at mass production.
The flotation plant design was based on extensive benchscale test work (including locked cycle tests) on drill core and many months of operation of a 30 t h2 1 pilot plant using the modified Cleveland Tin Mine processing plant. The Cadia concentrator was designed based on an extensive benchscale variability test work programme.
The Fluorspar Beneficiation Problem Acid grade fluorspar which is in great demand by the chemical and aluminum industries, must contain at least 97.5% CaF2 with not more than 1.5% SiO2 and 0.5% Fe2O3. Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO2. These limitations on grade and impurities require extremely close …

The concentrator studied processes ore from the UG2 platinum reef only – ore from the Merensky and UG2 reefs differ significantly in terms of mineralogy, therefore the focus is on UG2. UG2 ore has a higher chromite content, resulting in processing challenges, but can also contain higher concentrations of platinum group metals (PGMs).

In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking.
Every year the ore that is processed at the concentrator plant yields 269,000 tons of copper, 500,000 ounces of gold, 4 million ounces of silver and 28 million pounds of molybdenum production.
