The authors analyze the production of rice husks around the world and the production of silicon dioxide from rice husks. The research aims to analyze and forecast the production of rice husk and create a mathematical model to obtain silicon dioxide from it. The authors examine the problem of processing rice husk and obtaining silicon dioxide from it through mathematical modeling. The results of solving the Kolmogorov equation to obtain silicon dioxide from rice husk have shown that rice husk in the gross yield of rice in the Batken Region of Kyrgyzstan amounts to 36%, and silicon dioxide (SiO2) from this husk amounts to 64%. The percentage of rice husk from the southern region of the Kyrgyz Republic obtained using the Markov chain is compared with the percentage composition of rice husk from the same place obtained experimentally. The authors also established that low-temperature chlorine treatment of rice husk makes it possible to enrich silicon dioxide (SiO2) to 100% (i.e., to the maximum). The research materials are of practical value for obtaining technical silicon from the rice husk.
