Previous investigators have proposed a combination pyrometallurgical and hydrometallurgical process to treat the manganese silicate ores. The process consisted of arc melting the ore at 1,550° C and then rapidly cooling the melt by quenching it in water.
Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics.
The characteristics of each ore body are taken into consideration to define the most suitable beneficiation process. A combination of magnetic, heavy media and electrostatic separation and, in some cases, a flotation process is used to obtain the best andalusite concentrate.
