The first article in this issue titled “Return water improvement at Erdenet Mining Complex” considers the problem of reclaim water purification and conditioning efficiency increase, thus improving the metallurgical results. On the basis of thermodynamic analysis with respect to chemical processes of copper ions interaction with other components of waste and return water liquid phase, the required pH range was determined and a technology for joint conditioning of seepage water together with municipal purification works water and Power Plant ash-disposal area effluent water was recommended. The tests results showed a possibility for increase of copper and molybdenum recovery into marketable concentrate, as well as copper and molybdenum concentrates grade increase. Obviously, the proposed return water organization and purification system is distinguished by simplicity, and does not require any additional reagents.

While the above mentioned article describes the process improvement on the basis of the proposed technology, the article titled “Dialkyldithiophosphates of BTF series application in sulfide ores flotation study” presents the processes that with regard to efficiency are directly dependent on application of reagents and their characteristics. The extensive studies, conducted by the authors, permitted to synthesize aerofloats of BTF series, featuring different collecting properties. The results of laboratory and commercial-scale testing of BTF series aerofloats are presented, verifying, that in comparison with butyl xanthate they provide for a considerable increase in copper recovery from copper and copper-nickel ores, as well as total recovery of gold and silver from different types of silver and gold-containing ores. Launching the production of these aerofloats in Russia and their introduction at 11 facilities located in Russia and Kazakhstan are the merits of the authors of the article.

Theoretical insights are represented in this issue by the article titled “Improvement of approaches to vibratory screening process mathematical modeling”. The proposed method of modeling links fundamental physical properties of material with separation kinetics and screens’ design parameters. Modern mathematical methods and computer software programs are used in modeling. The article should catch the interest of a wide circle of specialists working in the areas of mineral processing and applied mechanics.

The authors of the article titled “Upon platinum group metals recovery from Cuban oxide nickel ores” stress the importance of considerable world reserves of nickel ores with diagnostically proven content of platinum-group metals, and raise a question of by-product concentration of platinum metals in nickel production. Cuban nickel production facilities are considered, as Cuba ranks among the countries with the largest nickel ores deposits. Cuban nickel ores and concentrates are characterized, and the ore processing technologies are described. On the basis of the literature references studies, a conclusion is made, that from the viewpoint of platinum metals recovery, Pedro Soto Alba plant sulfide concentrate is more promising.
