Iron ore deposits in Texas were first exploited commercially in the time when charcoal furnaces were profitable. Ores in Texas were used as early as 1855 at the Nash Furnace, believed to have been located in northwestern Marion County. Perhaps a score of furnaces were in operation at one time or another turning out iron for use in the manufacture of household articles and farm implements.

For example, after ore blending in a minetomill project, the Thalanga mine achieved higher recoveries in Zn, Cu, and Pb (McKee 2013). The purpose of ore blending is simply to provide uniform mill feed, so that the downstream processes can be finetuned, which aids in improving production efficiency and reducing production cost.
This research is aimed at the upgradation of indigenous Pakistani iron ore,, Dilband iron ore (hematite), by utilizing common metallurgical processes. First, the magnetic properties of the ore were determined. Initially, the iron ore samples contained 34 wt. % Fe in addition to other gangue materials. Therefore, the ore was subjected to a hightemperature reduction roasting process ...
