Distribution of iron and sulfur compounds: A case study of hydraulic waste fills

In view of increasingly difficult geological conditions of mining and due to shortage of mineral resources, the man has to find new sources of minerals. In the face of the growing interest in the deep sea mining and development of deposits in the areas of extreme weather, the most promising method to replenish mineral reserves and resources in many countries in the years to come is commercial-level processing of huge mining waste accumulations. Alongside with production of useful components, waste treatment can largely improve the environmental situation in mining and metallurgical regions. In Russia the major constraints of mining waste management are: inefficient regulatory and legal framework, lack of reliable information of the amount, composition and properties of waste, as well as the absence of special investigation methods for mining waste accumulation. Mining and processing waste has some peculiarities which should be taken into account in geochemical analysis, or in estimation of qualitative and quantitative figures on potential mineral raw material. Inclusion of the spatial variability in properties of waste accumulations, in the first turn, hydraulic fills, as well as the use of advance techniques of geostatistics and computer technologies considerably reduces the content of the required analyses, enables modeling of dumps, tailings ponds and other waste accumulations in compliance with the modern standards, and, consequently, allows cutting of total expenses connected with the research. Mineral processing waste (tailings, slag, etc.) are the most promising in terms of recycling. The models of agglomerated cake storage and the estimate of distributions of magnetite, pyrite and sulfur show that in hydraulic filling, despite segregation of materials due to sizing by gravity, some compounds are sufficiently uniformly distributed in a fill owing to the selected technology for formation of particle sizes. At the same time, minerals with high specific density (for example, copper and lead sulfides) tend to accumulating at the pulp slurry outlets. The revealed distribution patterns can improve quality of zoning of waste accumulations in accordance with their chemical composition and, thus, can help detect pockets which are most promising in terms of processing. At the stages of waste processing, these distribution patterns can ensure selection of an optimal processing sequence, and also will contribute to the efficient control over characteristics of mineral feed at all process stages.

Keywords: mining, fills and dumps, mining waste, geostatistics, waste processing, hydraulic fill, weighted distance discriminant approach, sulfides, tailings pond.
