The majority of mineral deposits are complex, i.e. composed of various minerals. In this case not only the main commercial mineral is mined, but also a number of co-products. As a rule, it is possible to achieve stable extraction of the main mineral, the concentration plant efficiency being directly depended on this issue. Production of co-products is a variable value as it is dependant on the direction and mode of mining operations. This results in disturbances in the concentration plant operation. Extraction of useful minerals from the ore is decreasing. Thus, production of coproducts should be stabilized through storing primary materials at storage areas. Such intermediate storages play an essential role in enhancing the ore grades. The paper offers a method to calculate basic parameters of storages for associated mineral products.
