The small concentrates which are turning out as a result of enrichment from ores of iron, non-ferrous 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, andalso 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 wastein 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.
