Development of a flowsheet for the beneficiation plant to treat 10,000 tons of iron ore per day at Barsua and the location of the proposed plant

Abstract

Based on extensive studies made on the beneficiation and sintering of Barsua iron ore (IR/236/62 of National Metallurgical Laboratory) and on the discussions held with the authorities of Rourkela Iron & Steel Plant, a flowsheet has been developed for the beneficiation of iron ore from Barsua mines. The proposed beneficiation plant is designed to treat 10,000 tons of -3” ore per day received from the existing feeders and Double Deck vibrating Screen-sat the Screening station in the Barsua valley can be advantageously utilized, after suitable modifications for wet screening as they have sufficient capacity for the proposed tonnage as given below:- Run of Mines ore crushed to -3”, is discharged from the main conveyor into a bin fitted with two heavy duty feeders feeding ore to two scrubbers at the rate of 360 Tons/hour- The scrubber discharge in each case is fed on to two wet double deck screens fitted with 1” and 1/8” screens. The plus 1” ore is conveyed to a bin with feeder for crushing it to minus 1” a tertiary crusher to be installed. The crusher discharge is wet screened on a double deck screen with 1/2 “and 1/8” screens. The plus 1/8” (about 6 mesh) material from each of the five screens is conveyed to a washed ore for heavy media separation.
