Parameters and conditions of crystallization for the majority of hypergenic and technogenic minerals have not yet been studied, as their determination is often difficult due to their imperfect crystalline structure (X-ray amorphous) and formation in polymineral compounds. The article discusses the formation conditions of 20 hypergenic and technogenic minerals from technogenic waters in the mining industrial system of the Kavalerovsky district tin−sulfide deposits (Primorsky krai) in Russia. For various ratios of hypogenic minerals−host rocks in ore and in tailings in a wide temperature range (from −25 to 45 °C), the Eh-pH parameters and the minerals paragenesis were established. All hypergenic and technogenic minerals formed during modeling were found and diagnosed in the Kavalerovsky tin−ore district mining industrial technogenic system.
