“…The microbial community in the heap (monitored by leachate analyses) varied during the first few months, becoming dominated by At. ferrooxidans and Desulfotomaculum geothermicum; other species identified were Thiomonas arsenivorans, Alicyclobacillus tolerans, and Ferromicrobium acidophilum [51]. Analyses of ore samples from the heap revealed At.…”

“…The Talvivaara deposit of polymetallic ores in Sotkamo, Finland, has become the most striking instance of heap bioleaching implementation for sulfide ores processing under the Far North conditions [49][50][51][52][53]. This deposit is considered to be one of the largest sulfide deposits in Europe situated in the geographical environment that closely resembles the Murmansk region in Russia.…”

“…The main silica-containing phases are quartz, mica, anorthite, and microcline [52]. Ore bioleaching in Talvivaara was studied during two decades: beginning from laboratory experiments in leaching columns, and up to construction of a pilot heap [49][50][51][52][53].…”

The authors describe the opportunities of low-grade sulfide ores and mine waste processing with heap and bacterial leaching methods. By the example of gold and silver ores, we analyzed specific issues and processing technologies for heap leaching intensification in severe climatic conditions. The paper presents perspectives for heap leaching of sulfide and mixed ores from the Udokan (Russia) and Talvivaara (Finland) deposits, as well as technogenic waste dumps, namely, the Allarechensky Deposit Dumps (Russia). The paper also shows the laboratory results of non-ferrous metals leaching from low-grade copper-nickel ores of the Monchepluton area, and from tailings of JSC Kola Mining and Metallurgical Company.
