Silicon slag ferro alloy

Silicon slag is a metallurgical material produced during the production of ferroalloys. Silicon slag is a by-product containing a certain amount of silicon. The silicon slag can be recycled and recrystallized for the second time, and finally purified to complete the reuse of the silicon material, which can make full use of the silicon slag and increase the value of the silicon slag. The first is to separate the obvious light-colored silicon slag and dark-colored silicon slag in the silicon slag with a technical hammer, and then use the principle of selective selection to further separate, so as to improve the silicon content in the silicon slag; then it is necessary to use chemical reactions to smelt and separate, mainly It is to separate impurities in molten silicon. If the requirements for silicon are not high, silicon slag can be considered. Both cost saving and effective. Silicon slag is used in the production of alumina. After desiliconization of the crude liquid, the solution contains a large amount of impurities such as silicon slag and red mud. Silicon slag is a by-product produced during the production of ferrosilicon. It can update and iterate the furnace temperature very well and increase the fluidity of molten iron.

After desiliconization, the silicon slag must be clarified and separated to produce a pure and transparent sodium aluminate solution. When processing the desiliconized solution, leaf filters or filter presses are commonly used in industry to separate the silicon slag in the desiliconized solution. The task of the silicon slag separation process is to separate the desiliconized slurry sent from the desiliconization process to obtain a sodium aluminate semen whose desiliconization index, iron-aluminum ratio and float content meet the process requirements.
