Geo-statistical methods for reserve estimation are difficult to use when stationary conditions are not satisfied. Artificial Neural Networks (ANNs) provide an alternative to geo-statistical techniques while considerably reducing the processing time required for development and application. In this paper the ANNs was applied to the Choghart iron ore deposit in Yazd province of Iran. Initially, a...

In the present study, characterization and beneficiation tests were performed on an iron ore sample to evaluation of separation efficiency (SE) different methods. Results showed that decrease in feed size fraction increases SE irrespective method. It was determined from liberation analyses increase values ​​at finer fractions is related with higher liberation. Calculated revealed operational pa...

As a result of the depletion high-grade manganese reserves, it has become necessary to consider exploitation low-grade ores. The main problem ore is low Mn/Fe ratio, which makes unfit for production ferroalloys. In this work, selective reduction technique was used smelting low-manganese in presence coke and fluxing material an electric submerged arc furnace obtain rich slag pig iron. product bl...
