Mining Monazite In Tailings

Steenkampskraal is a high-grade, hard-rock, vein monazite deposit with a resource that has recently been expanded by extensive drilling work, as reported in the mines ni 43-101 compliant mineral resource estimate.The underground in-situ average grade is 14.36.There are also surface tailings stockpiled as a result of previous mining and processing operations with a grade of about 7 treo.

Pillai says that depending on the monazite concentration in the raw sand, radiation exposures of the order of 0.13-1.00 man-milli seivert msv per tonne are involved in the mining and separation of monazite.Monazite contains 0.2 -0.4 per cent of uranium and 4.5-9.5 per cent of thorium which occurs as oxides depending on the region of occurrence.

It is the ore ilmenite, and not thorium, that the mining mafia is after in the beach sands of odisha, tamil nadu and kerala.Titanium, a strategic metal in demand in the nuclear power sector and the aerospace industry, is extracted from it.

The mining industry is a fundamental industry involved in the development of modern society, but is also the worlds largest waste producer.This role will be enhanced in the future, because ore grades are generally decreasing, thus leading to increases in the wastemetal production ratio.Mine wastes deposited on-land in so-called tailings dams, impoundments or waste-dumps have several.

The mining operation will be carried out with a mining fleet of two 100 mm blast hole drills, one cat 988h loader, one cat 385 shovel and four cat 773 off the road trucks, supplemented by support equipment such as tracked dozers, graders, water trucks, and emulsion tankers backed by other minor equipment.
