INNOVATIVE BREAD TECHNOLOGIES IN AN ACCELERATED METHOD WITH AND WITHOUT THE USE OF SOUCE AND YEAST

The article presents the results of a study of the possibilities of obtaining bread using accelerated technology, and the relationship between the obtained results of a study and the technological processes used to produce bread is considered. The express way of preparing dough on sourdough allows more efficient use of the main and additional raw materials in order to intensify the ripening of the dough and improve the quality of bread. Different technological processes of making bread were used and the revealed pattern between different technological processes, the addition of starters and the quality of bread was analyzed. As a result, the obtained bread products have high organoleptic and physico-chemical properties, corresponding to the prescription composition, and can be taken as the basis for the development of technical documentation for new types of enriched products

A study of the biohydrometallurgical method for extracting gold from flotation tailings

This paper shows the results of the comparative study of efficiency of gold extraction methods from technogenic flotation tails by agitation cyanidation and biooxidation followed by leaching. A representative sample of flotation tails was taken at gold extraction plant of Altyntau Kokshetau LLP. Experimentally, an increase in the efficiency of leaching gold from flotation tails during preliminary bacterial oxidation was found. By biochemical leaching, 72 % was extracted, which is 7 % more than using expensive sodium peroxide and 10 % more than using the traditional method of cyanidation

Research of biochemical gold recovery method using high-arsenic raw materials

This article contains the results of experiments to recover gold from complex mineral raw materials containing more than 15 % arsenic. Laboratory tests showed that standard cyanidation recovers only 26,4 % of gold into the solution. Additional oxidizing reagents used increase the leaching efficiency and enable to recover more than 40 % of gold during subsequent cyanidation. The efficiency has been established for replacement of cyanide with thiourea and thiosulfate solutions. 79,5 %, i.e. the maximum recovery rate, was found in the experiment with preliminary oxidation with T. Ferrooxidans, a bacterial culture, followed by leaching with a thiourea solution
