PAPER • OPEN ACCESSAbstract. A poor magnetite iron ore is a super large independent scandium deposit with over the multi-billion potential utilizable value. Shaking table separation is very useful for impurities removing and scandium content increasing as a follow-up step of high-intensity magnetic separation. In the present study, a satisfactory index, namely scandium content of 83.10 g/t and recovery rate of 79.45 wt%, was obtained by shaking table separation. The good result was achieved under the conditions which the parameters were feed concentrate of 18 wt%, feeding quantity of 11 L/min, stroke frequency of 275 times/min and stroke of 17mm.

Abatract. In this paper, a technique for non-conductive silicon heating and conductive silicon levitation is described. This research focuses on studying the effect of applied power on temperature of droplets during phosphorus removal from Silicon and ferrosilicon alloys (24%Fe-76%Si) by utilizing a refining process known as electromagnetic levitation with subjecting the levitated alloy to an argon-hydrogen gas flow. The effects applied power on temperature were observed and analyzed. The results of this investigation will use vacuum electromagnetic levitation technology solar grade silicon samples will be prepared from relative inexpensive raw material, metallurgical grade silicon.
