Research of lithium sorption by KU-2-8 cation exchanger from model solutions simulating geothermal fluids in the dynamic mode
- Authors:

The extraction of chemical compounds from hydromineral raw materials is currently a promising objective. The geothermal deposits in the Kamchatka Territory should be considered as possible sources of lithium, boron and other chemical compounds. Their economic efficiency is justified by the complexity of the use of resources of geothermal fluids. The article presents data obtained as a result of experimental studies of lithium sorption by KU-2-8 cation exchanger from model solutions that simulate geothermal fluids in the dynamic mode. It was shown that in the first phase of sorption, ion exchange results in the absorption of lithium and sodium ions by the hydrogen form of cation exchanger up to the degree of cation exchanger saturation by 78 %. After that, the displacement of lithium ions by sodium ions is observed. The intermediate solutions were obtained in which the molar ratio of Li/Na is 80 times higher than in the initial solution. To separate sodium and lithium, it is proposed to use the lithium form of cation exchanger obtained using a portion of lithium chloride concentrate. The separation occurs due to the displacement of lithium ions by sodium ions. The effluent has a molar ratio of Li/Na = 10.4. The regeneration is carried out with 1 n hydrochloric acid, while the concentration coefficient of sodium chloride equals three.

The problems of efficient use of the tumenian reservoirs at final stage of low-pressure gas production and prospects in their solutions
- Authors:
- O. E. Bugriy
The reserves depletion estimation is presented for main (base) fields in the north part of the Tumenian area. The significance of long time production of base fields is shown. The main problems of efficient use are shown for reservoirs at final stage of low-pressure gas field. The methodology associated with solving the problem is formulated for low profitability in low-pressure gas output. The recommendations for State support of subsurface users are prepared for efficient low-pressure gas production and efficient use of reserves at all.

Some facts of history of training and employment of mining engineers during 20-30th years of 20th century
- Authors:
- V. G. Afanasev
The article is dedicated to the problem of training mining engineers during the most difficult Soviet period. The problem was solved with foundation of new educational institution as well as reorganization of functional ones primarily Mining Institute. Reformation of universities was justified sometimes not. Disadvantage of reformation was repression to highly qualified specialists of mining. Personnel problem was solved that allowed to increase coal and oil extraction.

Examination of utilization of the earth’s interior is a wise use of mineral reserves
- Authors:
- Yu. A. Podturkin
The Russian economy is appreciably defined by the richest minerals -raw potential and effective strategy of its use. The major problems of bodies of the Government in sphere of regulation of attitudes protection of reserves is the objective economic estimation of stocks of minerals, their authentic state account, involving in development of a maximum quantity of minerals at existing economy and technologies, decrease in losses of minerals in extraction and processing, complex processing of raw material, prevention of cases of injurious working off of stocks.

The estimate of the utilization’s efficiency of the production waste products, which appeared as a result of the preservation of the environment measures
- Authors:
- E. M. Pronin
Nowadays the problems of the stable growth of mineral and source of raw materials and fuel and energy complex industries are attached great importance to, since it influences the country social-economic condition. In its turn the development of the mining industry requires opening up new lands, which are especially vulnerable to different kinds of anthropogenous and technogenous factors. The changes in the state of economic system have excluded the lowering expenditure by the economy of the production scale. The typical features of a new economy became the progress of free competition and intensive demonopolization. At the same time for the mining industry it is significant that large-scale enterprises should be the foundation of many cities economies of the Russian Federation. For the way out of a system crisis it is necessary to change the strategy – to alter not only the condition of the system, but its management. The formation of the mining complexes permits to use sources of raw materials of the exploited deposits in the proper way, to process waste products of the basic production into the commodity output, to raise the efficiency and cut costs of the preservation of the environment measures from concentration waste products, exhaust solutions, gases, warm water harmful influence on the environment. The practical use of the production waste products of the mining complexes is unprofitable and makes sense only because of its opportunity partially compensating the aggregate investments for the preservation of the environment. The estimate of the utilization s efficiency of the production waste products has made.
