Jun 04, 2020 Therefore, Jiao et al. proposed an innovative approach to recover iron from copper tailings via low-temperature direct reduction and magnetic separation, in which copper slag was reduced by pulverized coal and then recovered by magnetic separation, and the reduced iron powder with iron grade above 90 and recovery ratio of 95 was finally obtained. Generally, reduction and beneficiation of iron from copper slag.
Of the existence of FeS. The recovery body of copper slag was mainly copper matte, returned to smelting process of copper by means containing acid leaching, flotation recovery and depletion recovery.3,7,8) Copper slag con-tains large amounts of fayalite, direct magnetic separation of iron recovery is limited. Recycling method for Fe is.
Aug 10, 2019 The flotation-magnetic separation method could effectively recover copper and iron in copper slag . The content of magnetic iron oxide in copper slag was about 20–30 , while the main iron-containing phase of fayalite and other silicate phases entered the tailings during the magnetic separation process [ 6 ].
In summary, the Fe 3 O 4 and Fe 2 SiO 4 in the copper slag could be reduced to the metallic iron by coal-based direct reduction and recovered by magnetic separation. The best reduction conditions were those in which the reduction temperature was 1300 C, the reduction time was 30 min, the dosage of coal addition was 35 wt. , and the dosage of.
In the method, copper slag is mixed with a reducing agent, an additive, a binder, etc., and steps such as reduction roasting, crushing, screening, and magnetic separation are conducted, to separate copper, lead, and zinc in the copper slag, realizing comprehensive utilization of the copper slag.
Abstract An innovative technology for direct reduction-magnetic separation with the addition of Na2CO3 and CaO was studied to upgrade copper slag assaying 40.33 Fetotal and 0.65 Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.
Apr 01, 2019 Direct reduction-magnetic separation is an efficient way to recovery iron from copper slag, where iron and copper minerals can be transformed into the desired phases (metallic Fe and Cu) by direct reducing the mixture of copper slag and carbon as a reductant at about 1200–1300 C [, , ]. In the direct reduction process of copper slag, the fayalite and copper sulfide are reduced to metallic iron and copper, and the metallic copper.
