Abstract
Results are presented from the refining of metallurgical grades of silicon on the basis of hydrochloricacid leaching with ultrasound Such refining makes it possible to obtain silicon powder that is 9990 pure A study is made of the effect of various factors in the leaching process duration reagent concentration and the rate of mixing of the solution on the degree of purification of silicon powder by the proposed refining method and the process parameters are optimized to reduce the impurity content of the material that is being processed to 883–895
