The influence of mineralogical composition features on Severoonezhsk bauxite thermochemical enrichment

Article preview

The analysis shows a sharp aggravation of resource replenishment problem on the mining enterprises of the country. The share explored to date active bauxite stocks is 60-68 %. Provision of proven bauxite reserves has reached a critically low level, and a strategic reserve for existing fields is insufficient. The situation is aggravated by the lack of new mining facilities and the discontinuance of  exploration. While the resource base preparation in the volume, cost-effective for industrial development, requires 10-15 years with a concentration of significant resources. Unfortunately, in Russia there is no high quality bauxite, which is global alumina industry based on. One solution to this problem is to engage in the Bayer process production the low-quality bauxite with thermochemical pre-conditioning. Despite high energy costs, calcinations condition allows bauxite materials for a variety of technologically harmful contaminants such as organics, sulfide sulfur, carbonates, and post-treatment circulating alkaline solutions to improve the silicon module of bauxite concentrate. On the example of high-silicon chromium Severoonezhsk bauxite shows the positive role of calcinations in their processing and increase the possibility of multiple silicon module of bauxite ore, successfully processed by the Bayer method. Laboratory tests confirmed by the experimental-industrial tests.

Processing of manganiferous raw material producing high-quality product

Article preview

At the present time the demand of manganese is high in Russia. Metallurgy industry lacks of high quality manganese products. They make strict requirements to manganese concentrates for phosphorous content. It is possible to increase the quality of manganese concentrates and to use law-quality manganese raw material in the processing by means of hydrometallurgical processing.

Modelling of thickening process in mineral processing

Article preview

The present paper is devoted to the research of a spatially one-dimensional model of flocculated suspensions in the clarifier–thickener. This model unites a theory of sedimentation– consolidation processes of flocculated suspensions, which leads to a strongly degenerate diffusion equation, with the discontinuous flux. The development of steady-state concentration pro- files in a continuously operated clarifier-thickener is described. Numerical examples for construction of steady-state profiles and their applications for comparisons different modes of operation, to the control of sediment height are presented.

Application of air-permeability method for filterability prediction of different materials

Article preview

The article is devoted to research work, in which an attempt was made to apply the Blaine-meter for direct assessment of filterability of different materials. In the theoretical part of the article the main laws linking the Blaine index of the powder material and the average specific cake resistance are described. A number of experiments with materials taken from actual operating plants were carried out. To determine the Blaine-index the laboratory Blaine-meter was used, and to determine the average specific cake resistance standard tests of filterability on the batch pressure filter were carried out. As a result of processing experimental data and the necessary calculations direct relations between the Blaine-index and average specific cake resistance were obtained.
