Abstract
Technology of production of the pyrite cinders of molybdenum middlings includes: mixture granulation (composition 1: Mo-concentrate 90%, kaolin 10%; composition 2: Mo-concentrate, 97.3-97.0%, kaolin 2%, SK polymer 0.7%), their firing at 600°C to oxidize sulfide minerals and to recover rhenium oxide. As a result of Mo concentrate mixing with kaolin, a "dilution" of the pyrite cinders with Mo takes place in the case of composition 1. The search of pellet-forming scheme based on alternative to existing compositions binding agents that minimize this rate is of actual importance. A composition for the charge granulation providing light duty of the extraction of Re and Mo from the cinder is created. Its disadvantage is an increased alkalinity of the polymer solution, which leads to adhesion of granules and metal corrosion of the hearth furnace. Objective is to develop organic polymer, devoid of this shortcoming. The approach bases on a comparison of strength and technological characteristics of binders: kaolin and alternative to it of organic nature, being in the composition of pellets and cinder of Mo concentrate is applied. The SK-N product is proposed which is formed when the molar ratio of polyacrylonitrile: NaOH = 1.0: 0.6, in contrast to SK (1.0: 1.0), neutralized to pH 7 with H2SO4. The alternative ashless organic binders are selected for the same purpose: polyacrylamide-GS (PAA-GS) and NH4-CMC. Basing on the PAA-GS a new composition of the charge has been developed, % wt.: Mo concentrate 97.5%, kaolin 2%, polymer PAA-GS 0.5%, devoid of lack of charge with the SK.
