FIELD: metallurgy. ^ SUBSTANCE: procedure consists in leaching mineral raw material containing gold in water cyanic solution with active oxygen at hydro-dynamic effect facilitating cavitation mode at swirling flow of suspension of mineral stock containing gas and solid phase. Also, leaching is performed at increased rate of swirling of suspension flow till generation of the mode of super-cavitation in flow for destruction of crystal lattice of minerals and simultaneous after-crumbling solid phase with participation of free radicals of guaranteed electron of atomic oxygen and hydrogen formed in the process of super-cavitation. The transition reactor consists of an inlet branch, of a disperser with a connecting pipe for supply of oxygen into a united cavity of cylinder channels, of a cavitation chamber, of a cascade of hydro-dynamic emitters; of damping nozzle and of an outlet branch. Also, the disperser is made of porous material with nano structured pores structurally facilitating division of suspension into small flows. The cavitation chamber is made in form of an elastic collar controlling flow area into mutually perpendicular directions by means of clamping mechanisms forming a cascade of controlled hydro-dynamic emitters. ^ EFFECT: raised intensity of leaching gold. ^ 6 cl, 1 tbl, 5 dwg, 3 ex |
