NIETZ TECHNOLOGIES is a modern dynamically developing research center. NIETZ scientific developments are aimed to create effective and environmentally safe hydrometallurgical technologies for the processing of various raw materials.
NIETZ has experience in engaging other organizations to collaboratively develop complex process schemes that include enrichment and pyrometallurgical operations in addition to hydrometallurgical operations.
The Center is equipped with modern laboratory and chemical-analytical equipment, which allows us to perform all types of complex studies and obtain reliable results. The work is performed at the level corresponding to the requirements of the latest achievements of science and technology.
NIETZ research activities key areas
- Development of hydrometallurgical technologies for extraction of non-ferrous and precious metals from sulfide and oxidized ores and concentrates - copper, nickel, copper-nickel, lead-zinc and others.
- Development of hydrometallurgical technologies for gold and silver recovery from sulfide and oxidized gold-bearing ores and concentrates.
- Development of technologies for autoclave uncovering of refractory (including carbonaceous) gold-bearing ores and concentrates.
- Creation of hydrometallurgical technologies for processing hard-to-enrich, non-standard and anthropogenic materials (substandard concentrates, semi-products, waste, tailings, etc.)
- Carrying out large-scale semi-industrial tests on the autoclave pilot plant in the pilot shop (Blagoveshchensk).
- Determination of physical and chemical properties of ores, concentrates and products of their processing.
- Environmental hazard assessment of waste products. Determination of hazard classes by calculation method and biotesting.
- Analysis of existing production facilities and development of recommendations to improve their efficiency.
