FIELD: pretreatment of fine crushed fluorspar concentrates useful as flux in metallurgy. ^ SUBSTANCE: claimed method includes agitation of concentrate with 8-18 % humidity, calcium hydroxide or calcium oxide and treacle in wt % of 1-2 and 2-6 as reduced to concentrate mass, respectively. Obtained wet mass if extruded through nozzle, cut to the desired dimensions, dried for 10-30 min at 60-1200C, and held at positive temperature for at least 5 days. ^ EFFECT: method for agglomeration of fine crushed fluorspar concentrates with increased humidity to obtain product of desired strength. ^ 1 ex |
