Complex use of iron ores in iron and steel industry

Article preview

The most common inorganic pigment is red iron oxide. Production of red iron pigment from Yakovlevskogo ore deposit is promising and will meet the demand for high quality and in-expensive pigment. Designed wasteless flowsheet for separation of iron ore in two qualities –  paint grade quality (pigment) and metallurgical grade. The technology includes crushing, fine grinding ore in a ball mill and classification. The metallurgical grade of ore is used for metallurgical manufactures of briquettes.

Use of new kinds of disk concentration tables for increase of efficiency of gravity concentration

Article preview

One of the most effective gravity aggregate is concentrating tables. Concentrating tables are used for tin, tungsten, rare, precious metal ores  beneficiation. The new designs of rotating disk concentrating tables are developed. Comparative tests of concentrating shaking table, spiral sluice and of the basic experimental model of a rotating circular table were conducted for concentration of artificial mixtures. The using of round tables can increase recovery and efficiency of separation оf dense  particles.

Features of rich iron ores preparation for metallurgical processing

Article preview

Iron ores is one of the main types of minerals used used by mankind. Practically all domestic deposits contain 20-40 % iron ore and so are the deep concentration. Deposits of rich iron ores, containing more than 55-60 % in our country is not enough. One of these fields is Yakovlevskoye iron ore deposit. The use of dry magnetic separation of ore for the preliminary concentration did not give positive results. The study of grain-size composition  of  the  ore  showed a significant disparity in the distribution of iron by classes size that afford it possible to carry out preliminary concentration of ore screening. For ore processing flowsheet is proposed which includes crushing to a particle size of 10 mm, screening fraction of 5 mm. Larger fraction  of 5 mm is used, for example, in the blast-furnace process, and the fraction smaller than 5 mm is direct to the briquetting. As binding substance for briquetting used solution of carboxymethyl cellulose, or a combination of binder based on carboxymethyl cellulose or highly active   clay.

Working out of new designs of concentration tables for increase of efficiency of enrichment useful iskopae

Article preview

It was made new modification of device for allows increasing recovery, to increase productivity and to lower size of concentrated particles. The device has a deck executed as a disk, which divides into sectors; each sector has circular rifles. The table is equipped with the high-frequency step-by-step engine ensuring continuous rotation of a table and submission counter impulses for shear of particles in a direction to rotation of a table.

The unit for gravity concentration of fine particles

Article preview

It was made new modification of device for allows increasing recovery, to increase productivity and to lower size of concentrated particles. The device has a deck executed as a circle, which divides into two sectors; each sector has circular rifles with progressively growing height from the centre to periphery of a deck. The table is equipped with the high-frequency step-by-step engine ensuring continuous rotation of a table and submission counter impulses for shear of particles in a direction, opposite to rotation of a table. The quantity of angle sectors can be various. Testing of prototype of a table has confirmed an opportunity of increase of recovery, decrease size of extracted dense minerals and increase of throughput.

Recycling of solid domestic wastes

Article preview

Various types of human-produced waste, in particular municipal solid waste (MSW), on the one hand are major environmental pollutants and on the other hand often represent valuable products suitable for recycling and reuse. There are two main methods of waste reclamation: landfilling and recycling. Landfilling of MSW in landfills should be considered as a forced, short-term solution to the problem, in fact, contrary to environmental and resource requirements. Gradual transition from landfilling to industrial processing is the main trend in solving the problem of MSW utilization in the world practice.
