(VIMS) // rmo-vims@mail.ru THE GEOLOGICAL FEATURES AND PROSPECTS OF POOR ORE CHROME OCCURENCES AS EXAMPLIFIED IN KHABARNINSKY MASSIF OBJECTS (SOUTH URALS) The composition of chrome ores and ore-forming chrome spinels from rocks of DVK complex is characterized by higher iron content than other lithotectonic assemblages. Chromite concentrates which contain more than 40 % Cr2O3 and meet recovery and extraction requirements were obtained as the result of technological research of poor ores. This research also confirmed the expediency of significant reduction of Cr2O3 cut-off grade for the evaluation of chrome ore resources of the massif, which in turn increased their resource potential.For the first time the experimental melting of processed products was conducted and demonstrated the possibility of their use as metallurgical feedstock. Economic-geological evaluation confirmed the efficiency of inclusion of super-poor ores in processing and emphasized public interest in their study. Key words: Habarninsky massif, chrome ores, fromseriesid, enrichment of ores, ultrabazita, DVK complex, poor ores, economic efficiency, onboard contents. Р. 3-11

As a result of the visit by Russian geologists of these sites was selected the collection of stone material, which has been studied later by the optical and laboratory analytical methods. It has been defined that both uranium and gold with tellurium mineralization developed in metasomatic rocks of amphibole-quartz composition and accompanying skarnoids, obviously related with granitoid magmatism. The defined features of the ore sites should be taken into account during the exploration geological works in similar geological conditions. Key words: Northern Finland, uranium, gold, amphibole-quartz metasomatic rocks. Р. 11-17

According to this assessment, the general metal content of post-mining dumps is more than 400 tons. Inferred gold reserves of technogenic dump placers can be about 180 tons, with estimated gold grade more than 0.13 g/m3, or about 120 tons with estimated gold grade more than 0.3 g/m3.
