    Industrial silicon production is based on silica as raw material and carbonaceous raw material as reducing agent, which is smelted by electric furnace. Among them, industrial silicon is mainly used as raw material for polysilicon, monocrystalline silicon, silicon alloy, and organic silicon, with applications in aerospace, new energy, high-purity semiconductor and other industries, and the demand is increasing year by year. Industrial silicon in the process of smelting refined silicon in the average refining 1 ton of silicon water produces about 100 kg of silicon slag, so the number of industrial silicon slag produced each year is huge, for a long time silicon slag is used to pave the road or as a waste pile, not only occupy a lot of land resources, but also bring a series of environmental problems. At the same time, industrial silicon slag contains more than 15% of monomeric silicon, which is not utilized, resulting in a waste of silicon resources and bringing great economic losses to enterprises. In addition, there is also heavy adulterated silicon material in silicon waste that has been mixed with impurities such as B, P, Ga, Al, etc. In order to enhance utilization, it is also necessary to sort out the available silicon.   Industrial Silicon Smelting   Currently. For industrial silicon slag and mixed silicon waste processing methods are mainly manual sorting, re-sorting process, electromagnetic induction melting or back to the furnace re-refining way, which manual sorting by crushing large silicon waste, from which large particles of industrial silicon for recycling, the overall sorting efficiency is low, after sorting there are more high content of industrial silicon can not be recycled; re-election process requires the silicon slag grinding to a few millimeters, the process is complex, and also waste a lot of water. Also wastes a lot of water, and the separation effect is relatively general; electromagnetic induction melting or furnace melting, because of high energy consumption and silicon slag viscosity, it is difficult to directly separate out.   The existing recycling process of industrial silicon have certain problems, but the application of the latest sorting technology of artificial intelligence sorting machine, in the sorting can replace the existing silicon slag sorting process, to provide a simple and efficient sorting method, and enhance the industrial silicon recycling rate in silicon slag. The silicon slag only need to crush, Use artificial intelligence machine sorting directly, in the silicon slag recovery of industrial silicon sorting precision, sorting effect, sorting efficiency, recovery rate, recovery costs are better than the existing silicon slag sorting process.   The main working principle is that the silicon slag is crushed and dissociated, and the difference in surface characteristics between the slag and industrial silicon is used to identify good and bad materials through photoelectric sorting technology, and the good and bad materials are sorted out through the control system controlling the spray valve, so as to achieve the sorting separation of silicon slag and industrial silicon.     Before sorting   After sorting   At the same time, the artificial intelligence sorting machine has a great improvement in sorting compared with the ore color sorting machine, which can only judge good and bad materials based on color. In the silicon slag sorting, there is a coexistence of good and bad materials, small color differences, it can not identify the good and bad materials by color, artificial intelligence machine will not worry about this problem, through the identification of multi-dimensional characteristics of silicon slag,it establish the models, accurately identify materials with good sorting effect. So as to achieve the purpose of high-efficiency recycling of industrial silicon and increase the economic benefits of enterprises.   As a high-tech enterprise specializing in industrial ore sorting, Mingde Optoelectronics has mature technology accumulation for solving all kinds of industrial ore sorting problems, and the product application scope covers talc, fluorite, wollastonite, potassium feldspar, barite, quartzite, calcite, calcium carbonate, magnesite, lithium pyroxene, phosphate ore, gold ore, pebbles, quartz sand, coal gangue, vanadium ore and nearly 100 kinds of metal and non-metal. We have strong technical advantages in the field of ore sorting.   Edited by Jacky
