Ivestigation of conditions оf formation calcium hydrosulfasaluminates in the NA2O – AL2O3 – CAO – SO3 – H2O system
- Authors:
- V. M. Sizyakov
- E. V. Sizyakova
- E. V. Tikhonova
Calcium hydrosulfasaluminates (GSAK) is a component of cement. They are slowly formed together with the forming of the structure of cement in water solution at measurable temperatures (0-25 °C) during about 4-6 months. Slow rate of crystallization of GSAK wasn`t allowed to treat them as self-autonomy objects for use in various technological applications. The possibility of formation of GSAK (4CaO×Al 2 O 3 ×mSO 3 ×nH 2 O) is proved in an environment of saturated electrolytes – aluminates solutions of alumina production. They crystallize in a short time about 1-2 hours and retain their stability in long time about 24-36 hours. This allowed for us to identify ways of their industrial use.

Influence of improvement of quality of copper concentrates on efficiency of their processing
- Authors:

- G. V. Konovalov
At present time high grade and free-milling ore reserves have been exhausted in our country as well as in nearly all other countries in consequence of intensive development of nonferrous metal deposits. Relatively low-grade crude ore, which is deaf and therefore rebellious, is involved into processing. Moreover, after the collapse of the Soviet Union the more free-milling ores turned out to be abroad and so sulphide copper-zinc complex ores which are dressed with lower grade became the major sources of copper and zinc concentrate production in Russia. At the same time the metallurgical production is making higher and higher requirements to concentrate quality every year, and it is possible to meet the requirements only by application of mixed dressing, chemical, hydro- and pyrometallurgical technologies.

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.
