Mercury ore

MERCURY :

Mercury deposits are small and irregular, occurring sporadically as scattered deposits and often as veinlets. This precludes large-scale, highly automated mining methods.

How is mercury made

The most common method of ore recovery is underground mining, involving traditional drilling and blasting followed by scraping or mechanical loading into ore cars.

Due to the fact that most mined cinnabar contains less than 1 percent mercury, various mineral processing techniques such as jigging, shaking, screening, elutriation, and flotation have been employed to assess the ore.

Conventional flotation separation methods for sulfide ores have seen some success in the United States.

However, due to cinnabar's soft and friable nature, crushing and grinding the ore to reduce it to a size small enough for mineral liberation may result in significant losses as fine particles are lost in the flotation process.

While various methods are effective in producing higher-grade concentrates of cinnabar for roasting, they cannot compete economically with direct roasting of the ore either as mined or followin
