This research is aimed at the up-gradation of indigenous Pakistani iron ore, i.e., Dilband ore (hematite), by utilizing common metallurgical processes. First, magnetic properties were determined. Initially, samples contained 34 wt. % Fe in addition to other gangue materials. Therefore, was subjected a high-temperature reduction roasting process between 800 °C and 1000 °C. Additionally, separati...

In this study, a novel technology for the comprehensive utilization of low-grade iron ore is presented. For with Fe content 24.91%, pilot-scale study pre-concentration, suspension magnetization roasting, grinding, and low-intensity magnetic separation was conducted, an concentrate grade 62.21% recovery 85.72% obtained. The products were analysed using chemical elemental analysis, particle size ...

in this study based on image analysis, an ore grade estimation model was developed. the study was performed at a limestone mine in central iran. the samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. the images of the samples were taken in appropriate environment and processed. a total of 76 features were extracted from the identified rock sa...

Stockpiling and blending play a major role in maintaining the quantity and quality of the raw materials fed into processing plants, especially the cement, iron ore and steel making, and coal-fired power generation industries that usually require a much uniformed feed. Due to the variable nature of such materials, they even come from the same source and the produced ores or concentrates are seld...
