Tsvetnye Metally

The November issue of Tsvetnye Metally features a collection of three articles describing the results of scientific studies aimed at adopting the cutting-edge technology by and raising the performance and the product quality of Kola MMC. Thus, a new flotation circuit is described that involves process automation. One of the articles suggests adding scales to ensure an even dust feed and hence a stable size distribution in fluidized-bed furnaces aimed at minimizing the amount of cake generated, maintaining a consistent particle size distribution of the roasted nickel product and enhancing the line performance.

The Light Metals, Carbon Materials section examines the prospects of using thin-layer refining of aluminium, which could deliver an effective technique for a low-energy production of high-purity aluminium.

Of practical interest is the article published in the Materials Science section that focuses on a particular approach to heating up round copper-alloy blanks. The paper describes a continuous furnace with walking beams that are not water-cooled designed to heat up round cast blanks to the maximum temperature of 1,000 °C. The furnace is equipped with charging and discharging systems, and heat is controlled automatically based on thermocouple readings and charging and discharging modes. The furnace has been fully commissioned.

Another article published in the above section describes ways to utilize the copper scrap generated by foundries. The findings confirm the feasibility of utilizing iron-bearing copper waste to broaden the spectra of burden materials for producing low-alloy copper-iron alloys.

The Chronicle section features an article marking Sergey Lemeshev’s 120th birthday. This publication is a part of the project initiated by the Ore and Metals Publishing House and aimed at publishing articles on the humanities authored by experts whose primary activity is in line with the House’s technical focus.

The current issue gives information about the 5th International Workshop New Automation Means and Systems in Mining, Metallurgy and Ecology, which took place at the Soyuztsvetmetavtomatika Centre in Moscow.

The issue tells about a large-scale event devoted to the prospects of the Bakor R&D Centre. The editorial board and the editor’s office of the Ore and Metals Publishing House express their condolences to the family of Gennady S. Makarov.
