FIELD: process engineering. ^ SUBSTANCE: invention relates to modified resins to be used in selective separation of solid or ionic particles, say, metal cations, from water media. Method of separating clay from clay-containing ore with organic or inorganic admixtures comprises bringing water slime of clay-containing ore in contact with amino aldehydes resin comprising silane binder, and separating clay from said ore in or after contact by foam flotation of, at least, one organic or inorganic additive. Method of cleaning bitumen comprises bringing bitumen slime comprising bitumen and one or several soluble or insoluble additives in contact with amino aldehydes resin comprising silane binder, and separating clay from said ore in or after contact by foam flotation of, at least, one organic or inorganic additive. Method of cleaning water compound comprising water and one or several soluble or insoluble admixtures comprises brining said compound with in contact with amino aldehydes resin comprising silane binder to obtain resin-admixture complex, and separating said complex from water compound in or after treatment to produce purified water. Method of ore enrichment comprises processing of water slime of ore including valuable mineral and one or more admixtures with amino aldehydes resin comprising silane binder to obtain resin-admixture complex, and separating said valuable material from foam flotation water slime. Modified carbamide formaldehyde resin comprises silane binder with covalent bond with carbamide formaldehyde resin with molar urea-to-formaldehyde ratio varying from 1:2 to 1:3. ^ EFFECT: higher efficiency of treatment and enrichment. ^ 42 cl, 1 dwg, 4 tbl, 5 ex |
