The lead-barite-fluorspar ore requires grinding to 100 mesh for economic liberation of the minerals. Grinding is conducted in a Steel Head Ball Mill operating in closed circuit with a Morton cyclone classifier. The overflow minus 100 mesh passes to the lead flotation section.
Suitable for milling toxic and highly-abrasive materials since it can be used in a completely enclosed form.

Under the electron microscope, kaolin consists of roughly hexagonal, platy crystals ranging in size from about 0.1 micrometer to 10 micrometers or even larger. Crystals may take vermicular and book like forms, and occasionally macroscopic forms approaching millimeter size. Found in nature, kaolin typically contains modest amounts of other minerals such as muscovite, quartz, feldspar, and anatase. In addition, crude kaolin is frequently stained yellow by iron hydroxide pigments. It is often necessary to bleach the clay chemically to remove the iron pigment and to wash it with water to remove the other minerals in order to prepare kaolin for commercial use.
Alternatively, whole-ore cyanidation can be used to process themineralized material across the three different ore types. Testing in the 2018and 2019 programs have shown that 90% of the gold can be recovered in dore, butno copper would be recovered using this process. The testing in the twoprograms showed that the cyanide consumption is approximately 1.3 kilograms pertonne.
Horomill® is a ring roller mill which is a joint development by the French plant manufacturer FCB Ciment and the Italian cement producer Buzzi Unicem Group .

Carbide Ball End Mill for Graphite Machining, 2-Flute/Long Model.
The calcine is quenched, without liming, and pumped to hydroseparators which are in closed circuit with tube mills, where the calcine is ground to about 90 per cent minus 325 mesh. This overflow is thickened, filtered, repulped in cyanide solution, and cyanided by a conventional flow sheet.
The use of Grate Magnet has become indispensable when dealing with free flowing dry feeds, for they effectively trap ferrous impurities at the very beginning. Grate magnets are fixed in hoppers and can be easily maintained without loss of production time.
