Silicon slag is generally a ferroalloy product that is collected from the remaining portion of the original mineral after refining, and it also contains a certain amount of silicon. Silicon slag can be used to return to the furnace to recrystallize, purify, etc., the important thing is that silicon slag contains more than 15% of the single silicon, mostly used for purification of industrial silicon. Silicon slag how to purify industrial silicon:
To separate the obvious light-colored slag and dark-colored slag in the silicon slag with a manual hammer, and then further separated by the principle of medium selection to improve the silicon content in the silicon slag;
Then melt separation, mainly to separate the impurities in the molten silicon. Silicon slag used in production is sorted by hand and then flushed by vibrating screen to fall into the machine sorting workshop, and then transported by forklift to the batching workshop for metallurgical material batching, and then loaded into ton bag after batching, and then transported by forklift to the melting workshop, and then transported by crane to the furnace operation platform, and then dosed by hand.
