Enrichment Process

For the purpose to solve the problem of reducing the negative impact of mining and processing production on the environment that is relevant for most mining regions of Russia, options of geotechnological strategy for mining of iron ore deposits on the basis of an ecologically balanced integrated underground geotechnology of extraction and processing of iron ore, which allow to utilize the entire volume of mining and processing waste in the mined out space and transfer the most environmentally hazardous enrichment process under the ground, have been formed. Technological schemes for chamber excavation of floors in ascending order have been developed, which make it possible to abandon the formation of ore pillars, thereby increasing the extraction of ore from the bowels, and using the worked out space for waste storage in the form of a dry backfill. Based on economic and mathematical modeling and a comprehensive assessment according to the environmental and economic criterion for the conditions of mining in a new step of one of the largest iron ore deposits in Russia the most effective option of geotechnical strategy has been established. Use of an ascending-descending order of floor mining with an optimal ratio of mining systems with laying out the worked out space and systems with collapse depending on the content of the useful component in the ore mined, the amount of space mined current tab and the volume of tailings used as backfill material, allows to utilize the entire volume of mining and processing waste in the mined out space and effectively to develop of reserves in a new step.

Volumetric Content

The disastrous Chi-Chi earthquake struck Taiwan on 21 September 1999 and resulted in the creation of more than 20 million cubic metres of demolition waste, which was stored temporarily at several sites. To reduce the site clearing costs, the inert materials (concrete, brick, pottery, and fines) in the wastes should be reclaimed and recycled immediately; but most of their properties were not known. Therefore, this study investigates the properties of demolition wastes, including inert materials, coarse portions, and fines obtained from two earthquake demolition waste storage sites (Puli and Tali) and one normal urban construction waste storage site (Taichung). It is found that the volumetric content of inert materials from earthquake demolition waste is about 96%. Such inert material is classified as having an excellent subgrade rating and can be reused as subbase and base soils. The abrasion level of the coarse portions of inert materials from the three sites meets the required level of coarse aggregate according to Standard Taiwan Code CNS-490. On the other hand, the maximum dry unit weights of fines of inert materials from the three sites are greater than 14.7 kN/m3, and their shear strengths are higher than that of the same classification group (SW–SM) of natural soils, so they can be reused as construction soils.
