PROSES UNTUK MEREDUKSI KWANTITAS AIR YANG TERKANDUNG DALAM PULP DARI BIJI OKSIDA DENGAN PENYOKONG NIKEL

摘要

Method for reducing water content of mineral nickel iron oxide pulps comprises diluting pulp with water; and injecting flocculant based on acrylic acid copolymer. Method for reducing water content of mineral nickel iron oxide pulps comprises successively diluting pulp with water to concentration less than 150 g, preferably less than 80 g solid l-1; injecting diluted pulp with dilute aqueous solution of preferably less than 0.5 gl-1 organic flocculant based on weakly anionic copolymer derived from acrylic acid with average molecular weight = 2*106 - 3*106 in doses of 50-1000 g per ton of dry material in pulp, to obtain upper layer containing 100 mg l-1 solid and lower layer containing 300-450 g l-1 solid; and then separating the two layers.
