The small concentrates which are turning out as a result of enrichment from ores of iron, nonferrous and other metals, as a rule, are unsuitable for direct use in melting or in other technological processes. Complex and rational use of mineral raw materials, fuel and energy resources is an actual problem in the industry of Kazakhstan. The development of domestic manganese ore and the expansion phosphorus manufacturing become particularly urgent. To improve raw material and fuel energy displays there was set a goal of using waste of different enterprises including fine fraction of phosphorus and manganese ones, and also waste coal as fuel. The use of these wastes allows for phosphoric subsector to obtain fluxed phosphorus sinter and out of it yellow phosphorus and ferrophosphorus with an increased content of manganese. In this regard, organization of complex production of phosphate sinters with the usage of manganese ore and mining waste undoubtedly is of particular interest. The ferrophosphorus obtained after electrothermic processing can be used as an alloying element in steel smelting as contains a significant content in the manganese. In the given research as the solid fuel are applied coal waste of Lenger deposit recycling of which is possible by increasing the extent of their use. It should be said that the level of waste coal is extremely low as yet. Using coal mining waste in the chemical and metallurgical industries is highly effective for replacing a flux component and reducing the cost of expensive coke. Here are the research results of the joint agglomeration of phosphate and manganese ores with use of coal waste as a fuel. To determine the optimal process conditions the method of mathematical planning of experiments is used. It has been found that an increase in manganese ore in the sintering mixture contributes to the strength of the sinter, and increase in coal mining waste reduces the strength of the sinter.

One of the actual problems of the phosphoric industry is complex usage of all got raw materials and processing of technogenic waste with receiving products. One of the main waste of phosphoric production are the phosphorus-containing sludges which are formed on stages of condensation of vaporous phosphorus. Despite numerous researches on suppression and processing of phosphoric sludges, today the universal way of their processing meeting the requirements of phosphorus production isn't found yet. In this regard, we offer a sorption method of phosphorus release from phosphorus-containing sludges. Various alumosilicate minerals, including bentonites, vermiculites, refractory clays, etc. can act as sorbents. The specified minerals possess high sorption ability with an advanced surface. Results of thermodynamic researches of heterogeneous system phosphorus -water -solid mineral impurity are given. The thermodynamic probability of the main of reaction and systems characteristic for sorption process of phosphorus release from sludges is shown. For modifying the surface of minerals of the montmorillonite group entering into bentonites and vermiculites acid activation is used. For increase in hydrophilic surface of minerals are considered exchange cations of Al +3 , H + , Na + . It is shown that hydrophilic materials can be received at normal saturation by exchange cations. At its supersaturate hydrophily can reach initial (before processing) values.

Physico-chemical studies of chemical, mineralogical and phase features of Darbaza clay and swelling agents of oil sludge have been carried out to study the multifunctional sorption properties of local bentonite clays. The contents of the mineralogical and organic part of oil sludge were determined with physicochemical studies. As a result, it was determined that paraffin-naphthenic and aromatic compounds predominate in the organic part and the compounds of silicon, calcium, aluminum and iron predominate in the mineral part. Carried out studies of the modification method of local bentonites with acidic and thermal treatment, which activate sorption properties, are due to the cation exchange of the initial elements of montmorillonite minerals.

This article provides information about the method of obtaining potassium humate obtained from brown coal of the Lenger deposit, and also describes the elemental and mineralogical composition of potassium humate determined with SEM (JSM-6490l V, Jeol). Kinetic data on the decomposition of brown coal with solutions of potassium hydroxide are presented. The area of chemical reactions and the activation energy are determined. The benefits of the obtained potassium humate are that they are environmentally safe and have high bioactivity. They are also characterized by a high content of humic substances that are involved in the structure formation of the soil, accelerate biochemical processes, and increase the physical and chemical characteristics in the soil. Under the influence of humate-containing substances, the function of microflora elements in the soil is activated, and the number of beneficial microorganisms increases.
