Concentrating Mill Wastes are the Source of Pollution of Human Environment and Natural Ecosystems with Heavy Metals: A Case Study in Primorsky Krai, Russian Federation

<div>The prevailing mineral forms in mature concentration tailings; (a) isometric grains of galena in pyrite metacrystals, eroded pyrite crystal, and new formations of iron sulfates; (b) plumbojarosite and other hypogene and hypergene minerals: Bt, biotite, Gn, galena, Py, pyrite, Qz, quartz, Sp, sphalerite, Pb-jrs, plumbojarosite, and FeSO<sub>4</sub>xH<sub>2</sub>O in the form of cementing phases.
