Quartz Crusher is an AIM listed mining and exploration operation focused on Greenland and its mineral resources. The company owns two mines in Greenland, the Nalunaq gold mine and the Black Angel zinc and lead mine, and have recently announced that it has commenced production at its Nalunaq gold mine.
The Mosh hardness of quartzite is 7. After quartz crusher crush, it can use as all kinds building stone, especially outdoor stone such as paving stone, ballast stone , stone floors etc.
Compact structure, an ideal material for crafts stone carving, especially the pure color quartz.
Quartz Crusher are widely distributed, easy to mining , easy to process, low cost, is high rate of costs stone products.
Quartzite have wide range of uses, it is an important raw materials in manufacturer glass, ceramics, metallurgy, chemicals, machinery, electronics, plastic, rubber, coating industries.
Industrial use of quartz stone:
Most Marble Crusher contain 90 percent or more quartz, but some contain 99 percent and are the largest and purest concentrations of silica in the Earth's crust. Pure quartzite are a source of silica for metallurgical purposes and for the manufacture of brick.
Marble stone is a decorative stone and may be used as paving blocks, cover walls, roofing tiles, a flooring, stair steps, riprap, crushed stone, and roofing granules. quartzite crushed by quartz crusher such as impact crusher and cone crusher is also quarried for using in road construction and for railway ballast. High purity quartzite is used to produce ferrosilicon, industrial silica sand, silicon metal and silicon carbide.
For people who has Marble mines, our quartz crusher such as PFW series hydraulic impact crusher is an ideal crusher equipment to crush stones whose Mosh hardness is less than 9, after the primary crusher, our cone crusher can be used to crush the quartzite more fine. If is not convenient for you to transport the Marble stone out of the mine site, our portable crusher can resolve the problem too.
Marble Crusher was formed in 1998 as a mineral exploration company with specialist interests in tantalum. At that time the company was called Angus & Ross. It had exploration activities in Canada, China, Brazil, Australia and Greenland but none proved a mineable resource, except for the zinc/lead deposit in Greenland being the former Black Angel mine as operated by Cominco and for a short while by Boliden before closing in 1990.
A JORC resource study in 2007, prepared by Wardell Armstrong International reported a resource of 4.425 tonnes at an average grade of 11.6%, of which 8.6% is zinc and 3 % is lead. Included in the resource is a proven reserve of 1.489 tonnes at an average grade of 13.6% and a similar proportion of zinc and lead.
In early 2007 the company negotiated a loan facility, from a New York based hedge fund, to fund the Quartz Crusher of a bankable feasibility study, which was completed in January 2008. By May of that year the company had applied for and been granted a mining licence and was raising project finance to develop the mine. The banking crisis and falling commodity prices resulted in the withdrawal of the Marble Crusher and the company was then almost certain to go into default on the loan it had drawn on for the feasibility study.
