Nietz Technologies

What Nietz Technologies does

Nietz Technologies (legal entity: OOO NIIC Gidrometallurgiya / LLC SRC Hydrometallurgy) is a privately held Russian research and engineering services firm founded in 2008 and headquartered in Saint Petersburg, with a co-located Autoclave Pilot Plant at JSC Pokrovsky Mine in Blagoveshensk. The company specializes in hydrometallurgical processing of mineral raw materials containing non-ferrous and precious metals, with a focus on refractory and double refractory gold-bearing concentrates processed via autoclave pressure oxidation (POX) at up to 250°C and 4.5 MPa. Its offering spans four integrated service lines: laboratory research activities (including semi-industrial pilot testing of polymetallic ores and concentrates), full-cycle project support for hydrometallurgical capex programs, accredited analytical laboratory services through the Laboratory of Analytical Control (covering 60+ elements via fire assay, ICP-MS, ICP-OES, and AAS), and pilot-plant services backed by a Pyrometallurgical Pilot Plant with a Nabertherm rotary tubular furnace.

The commercial model is professional services: project-by-project bids, customized technical proposals, feasibility studies, pilot trials, and full engineering support from initial data development through commissioning and operational optimization. Customers are predominantly mining and metallurgical enterprises — led by the flagship Petropavlovsk Group / JSC Pokrovsky Mine relationship that yielded the 2018 Pokrovsky POX Hub commissioning — and also include PJSC MMC Norilsk Nickel, JSC Polyus Krasnoyarsk, PJSC Seligdar, AO Uralelectromed, OJSC Krastsvetmet, JSC Irgiredmet, Fincraft Resources (Kazakhstan), Kazakhmys entities, and Meta Nickel Cobalt (Türkiye). The firm protects its position through nine granted Russian patents, an internationally accredited analytical lab, 350+ scientific publications by its founder, and a deep bench of PhD-level metallurgists. Pricing is not publicly disclosed; channels are direct enterprise sales and earned reputation through scientific conferences (World Gold, MINEX, ALTA, the Non-Ferrous Metals International Congress). The company is privately held, founder-managed, with no disclosed external institutional ownership.
