Abstrakty
The results of laboratory simulation of heap leaching of non-ferrous metals from dumps of the Allarechensk deposit, low-grade ore of the Nyud-II deposits, and processing wastes of the “Kola MMC” JSC are presented. It is known that cut-off grade sulphide ores from both abandoned and currently developed deposits, overburden rock and dressing tailings, while being a major source of non-ferrous metals, pose a serious environmental hazard if unprocessed. So, any reasonable utilization of rock waste dumps, tailings and unfreed ore is beneficial both from environmental and economical viewpoints. Such natural and man-made resources can be processed using heap leaching whereby a sulphuric acid solution, an oxidizer (oxygen, iron (III) ions etc.) and microorganisms (Thiobacillus ferrooxidans, Thiobacillus thiooxidans etc.) are fed both onto a heap surface and interior. Uniform spreading of the solution is achieved via a system of pools, drain gutters, networks of half-socket pipes, or spraying. The enriched solution leaking from under the heap is collected in gutters or pipes and sent to further processing.
Przedstawiono wyniki badań laboratoryjnych ługowania metali nieżelazowych z hałd złoża Allarechensk, ubogich rud w złożach Nyud-II, oraz przetwórstwa odpadów „Kola MMC” JSC. Jak wiadomo, odpady o niskich zawartościach metali, których eksploatacja jest nieopłacalna, mogą stanowić poważne ryzyko dla środowiska. Dlatego rozsądna utylizacja składowisk odpadów jest korzystna zarówno pod kątem środowiskowym, jak i ekonomicznym. Tego typu naturalne i sztuczne źródła surowców mogą być przetwarzane z wykorzystaniem ługowania na hałdzie, gdzie roztwór kwasu siarkowego, utleniacz (tlen, jony żelaza (III) etc.) i mikroorganizmy (Thiobacillus Ferrooxidans, Thiobacillus Thiooxidans etc.) są dawkowane zarówno na powierzchni, jak i wewnątrz hałdy. Równomierne dozowanie roztworu uzyskuje się przez system basenów, rynien, sieci rur połówkowych lub rozpylania. Wzbogacony roztwór wyciekający spod hałdy jest zbierany do rynien lub rur, a następnie podlega dalszej obróbce.
