FIELD: oil and gas industry.
SUBSTANCE: invention relates to the technology of producing ceramic proppants, in particular to preparing raw material charge, which is used in the production of medium density proppants. In the method for manufacturing charge with the MgO content of 18-28% by weight, including calcining and cooling serpentinite, co-milling it with quartz feldspar sand to the fraction of less than 80 mcm, said cooling of serpentinite is carried out at a rate of 350°C/h and more, the total content of enstatite and protoenstatite in the cooled material not exceeding 33 vol.
EFFECT: increasing the charge grindability.
