Concentrating the chromium in chromium slag and improving the chromium–iron ratio is beneficial for the further utilization of chromium slag. In this paper, chromium slag obtained from a chromite lime-free roasting plant was used as the raw material. Pellets made of the chromium slag and pulverized coal were reduced at different pre-reduction temperatures and then separated by a melting separation process or magnetic separation process, respectively. The mass and composition of the metallized pellets before separation, along with the alloy and tail slag after separation, were comprehensively analyzed. The experimental results showed that the output yield of alloy, iron recovery rate, and chromium content in the alloy were all higher when using melting separation than when using magnetic separation, because of the further reduction during the melting stage. More importantly, a relatively low pre-reduction temperature and selection of magnetic separation process were found to be more beneficial for chromium enrichment in slag; the highest chromium–iron ratio in tail slag can reach 2.88.

Partial Abrasion

Low-traumatic technology of grain separation from an ear is developed. It consists in influence of an air jet on an ear.It leads to rolling of an ear on a surface of the threshing device concave and causes its partial abrasion which is followed by grains separation. Process of wheat ears low-traumatic threshing in the experimental device yields satisfactory results, provides reduces grain endosperm damage on 10-12% in comparison with traditional technology. Germ of grain damage decreases by 5%.Crushing of grain made no more than 0,5%. Use of the developed technology of the low-traumatic threshing will allow to reduce grain damage of cereal crops in case of the harvesting. It is important by cereal breeding.
