2. Concentration process of anatas mechanical concentrate for the purpose of obtaining synthetic ruby with low content of radioactive elements and rare earth elements

摘要

These include: (a) burning the anatasa concentrate between 400 and 600 ° C in 15 to 60 minutes, in which case the ferric oxide hydrate is converted to blood after pumping; (b) using H2, natural gas or any carbon reducing solid (metallurgical coke), reducing the burnt product from 400 to 600 ° C for 5 to 30 minutes in 5 to 30 minutes. 1. Carbonate, petroleum coke, graphite) convert mercury to magnesium; (c) use 600 to 800 Gauss magnetic field to separate the dry magnetic field or sparse magnetic field of the thin product, and remove (b) the magnetic component produced;(d) separation of dry or wet magnetic from low-density non-magnetic products with magnetic fields between 10000 and 15000 Gauss and extraction of silicates from silicates, diphosphates, monkeys, calcium, zirconium and minerals containing u and H; and 1. Dissolve 20-25% w / W HCl, 90-107 ℃ and 2-4 h, and extract impurities rich in faith, phosphate, Mg, Ba, Ka, sir, rare earth, u and th; (f) filtration and leaching products; (g) drying and filtration products; (H) oxidation and drying products 900-1200 ℃; (I) cooling products oxidized into compressed water or air;(J) leaching at 135 ° C with 25% w / W HCl or 55% w / W H2SO4 solution; (k) filtering the product; and (L) drying the filtered product by recovering the non-magnetic part such as rutile compound (final product);
