ABSTRACT
In clause the results of enrichment of technological tests of ore of a deposit Tebinbulak are resulted. Are executed gravitation and magnetic separation experiences. As a result of the executed tests recommended scheme for processing ore is magnetic separation. Under this circuit is received the iron concentrate containing 56,14 % of iron at extraction of it 41,84% from ore.
Keywords: Gravioconcentrate, Tails, Ore, gravity concentration, extraction, magnetic separation, Grinding to various sizes, Non-magnet. Fraction, deposit
We in [1] presented the results of studying the material composition of an ore sample from the Tebinbulak deposit.
This paper presents the results of the enrichment of the specified ore sample [1-9]. The ore was beneficiated by methods of gravity, dry and wet magnetic separation. Table 1 shows the results of gravitational concentration of ore at different grinding sizes [10-18].

Experiments were carried out on dry and wet magnetic separation of samples (Pic.2). For dry magnetic separation, the current strength was 0.25-0.5 A, for wet magnetic separation - 5-7 A [19-24]. The results of experiments with dry magnetic separation of ore are given in Table 4, for wet magnetic separation - Table 3.

With dry magnetic separation, the best result is obtained with magnetic separation of ore with a size of -0.5 + 0 mm at a current of 0.25A [25-28]. Under these conditions, a concentrate was obtained containing 40.95% of iron with an extraction of 57.71%.

Based on the studies performed, wet magnetic separation with the release of iron concentrate is proposed for the processing of ore from the Tebinbulak deposit. According to the recommended scheme, a magnetic fraction was obtained containing 56.14% of iron while extracting it 41.84%. Ore can be classified as refractory type.
