Silicon slag generally refers to the ferroalloy product collected from the remaining part after the extraction of raw ore, which also contains a certain amount of silicon. Silicon slag can be used for recrystallization, purification, etc. The important thing is that silicon slag contains more than 15% elemental silicon, and it is mostly used to purify industrial silicon. How to purify industrial silicon with silicon slag:
It is necessary to separate the obvious light-colored slag and dark-colored slag in the silicon slag with a manual hammer, and then use the principle of middle selection to further separate to increase the silicon content in the silicon slag;
Then smelting separation is carried out, mainly to separate the impurities in the molten silicon. The silicon slag used in production is manually sorted and then flushed by a vibrating screen and falls into the machine sorting workshop. It is transported to the batching workshop by a forklift for metallurgical material batching. The melting workshop is transported to the furnace operation platform by a crane, and the materials are manually fed.
