The gradual depletion of high-grade iron ores has necessitated the exploitation of low/off grade iron ore reserves . (ideally it should be < 1) is detrimental to blast furnace as well as sinter plant productivity. Indian iron . Study of the hand picked iron ore samples indicated that the ores can be grouped into three ore types. 1.
Next to hand picking, gravity concentration is the oldest of all forms of mineral processing. While, in the twentieth century gravity concentration has been partially replaced by other processes, notably flotation and magnetic separation, they have not made it obsolete. That such an ancient and inherently simple process has.

Hauled to the plant. There are a number of preparatory and support operations, which might or not be required, depending on mining method and other ... Hand-picking. In case of large grade contrasts or good visual distinction, hand- picking is a very effective way of up-grading, although in countries with high labour costs,.
CDE iron ore processing plants reduce alumina and silica contamination and increase efficiencies in steel production.
Consists of 4 Wood, 3 Iron and 2 strings. Wood is only obtained when a tree is struck with an axe or a pick-axe. Iron is found when mining rocks or Iron Ore veins.
