摘要： The invention relates to a dry method for obtaining coated crystalline silica with reduced toxicity. Crystalline silica presents mainly in form of quartz, cristobalite and tridymite, being quartz, by far, the most common of them. The invention belongs to the raw materials processing industry, in particular to companies that process crystalline silica as quartz and other quartz-containing materials (hereafter 'quartz') and to the industrial sectors that use powders of these compounds.
