METHOD OF EXTRACTION OF GOLD AT HYDRO-MECHANIZED MINING OF OXIDIZED ORES OF WEATHERING CRUST Russian patent published in 2003 - IPC

Abstract RU 2217236 C1

FIELD: mining of weathering crust and placers. SUBSTANCE: proposed method includes washing-off, disintegration, gravitational concentration at sluices of deep filling, screening, gravitational concentration at sluices of shallow filling, cleaning-up of concentrates from entrapping surfaces of sluices and conditioning of concentrates. Tailings of shallow filling sluice are directed for classification and classification sands are directed for grinding and then to shallow filling sluice. Concentrates of deep and shallow filling sluices are finally ground after preliminary classification and are graded into narrow classes of sizes which are separately concentrated at gravitational apparatus. Washing-off and disintegration on horizontal and inclined tables of hydraulic buddle are performed by hydraulic giant by rotary mixing water flow with clay nodular ore and washed-off ore is thrown in pile. EFFECT: increased extraction of concentrate. 3 cl, 1 dwg
