Research on exploration of mineral processing for a iron ore... Iron ore minerals are mainly silicate-type iron minerals in raw ore, and its distribution rate was 51.93%;...
→leaching of manganese ore from northeastern vietnam by reduction with so2 gas in an h2so4- rich solution... Compared to a conventional process, where Mn ore is heated to about 1,000 oC to convert MnO2 to MnO dissolved in hot sulphuric acid, extraction of Mn from the raw ore using SO2 gas as a reducing agent in an H2SO4 overcomes all the disadvantages, such as, high energy consumption, environmental pollution and loss of Mn (Everett, 1976)....
Application of arena computer program for computer simulation of the underground mine transport... A simulation of the model that simulates the real transport process of the raw ore material between two main transportation levels, connected with a central ore bunker, was made....
Optimizing transport in surface mines, taking into account the quality of extracted raw ore... In the following sections of the article a model solution is presented with the use of newly created program for optimizationof transport, taking into account the required quality of extracted raw ore....
