Abstract

The purpose of these studies is to study the forms of finding copper-porphyry ores of the Yoshlik I deposit compared with the Kalmakyr deposit data and to decide on the choice of a cost-effective ore processing technology. As a result of the studies, it was revealed that ore mineralization is represented by sulfides of various metals and iron oxides. The primary sulfides are pyrite and chalcopyrite. In the «Yoshlik-I» sample, the pyrite content is six times less than in the Kalmakyr sample and is 0.7%. The mass fraction of chalcopyrite in the Kalmakyr and “Yoshlik-I” deposits is 1.1 and 0.8%, respectively. The remaining sulfides of various metals and the minerals of these ribs are present in several single signs. According to the content of cell fids, the Kalmakyr ore sample is characterized by a small-sulfide ore; the «Yoshlik-I» ore sample is a slab-sulfide type ore. According to the oxidation state calculated by iron, ore samples of the Kalmakyr and «Yoshlik-I» deposits belong to the mixed variety of ores.

Highlights

Uzbekistan is rich in all types of minerals
There is a decrease in grinding tone, mainly an increase in the size class of [5,6,7,8,9,10] μm from 16.53 to 21.66%
It was established that in samples of ore of the «Yoshlik-I» and Kalmakyr deposits with a size of 65 and 70% of the -74 μm class, the share of chalcopyrite grains with an opening degree of less than 30% is 9.95 and 13.05%, respectively

Summary

Introduction

More than 1,600 mineral deposits have been developed and registered on the state balance sheet of the republic, of which more than two hundred are these deposits of non-ferrous, noble, and rare metals. Their gradual involvement in operation contributes to the growth of the industrial potential of the republic [1]. The «Yoshlik-I» copper-porphyry deposit is under development This requires survey work to study the material composition and determine effective technologies for processing the ores of this deposit. The analysis and study of existing copper ore processing technologies, their improvement, and adaptation for the conditions of new deposits in the Almalyk region are very urgent tasks [2-4].
