As a pure natural stone with high usage value, river gravel is formed in the long-term impact, squeeze and friction function. River gravel generally shows the color of black, white, yellow, red, green gray, etc. 

Application Area:Building materials, chemicals, fertilizer, metallurgy, mining, refractory, ceramic, steel, thermal power, coal, etc.

quartz with the color of black, dark gray and dark brown is a common basic volcanic rock mineral. With advantages of good corrosion resistance, compression resistance and oxidation resistance, quartz is widely used in roads, railways, construction, buildi

Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible Of the antimony ores proper the major mineral is antimonite Sb2S3 which contains up to 714 percent Sb in rare cases antimony ores are represented by complex sulfides of antimony

antimony ores and concentrates A native element antimony metal is extracted from stibnite and other minerals Antimony is used as a hardening alloy for lead especially storage batteries and cable sheaths also used in bearing metal type metal solder collapsible tubes and foil sheet and pipes and semiconductor technology

Antimony ores and concentrates are the 3561st most traded product and the 4547th most complex product according to the Product Complexity Index PCI The top exporters of Antimony ores and concentrates are Russia 50M Tajikistan 44M Australia 436M Burma

While antimony concentrates assaying less than 50 antimony may be salable such lowgrade concentrates require special arrangements with the smelters Smelter returns for antimony concentrates are based on a sliding scale which provides for 65 Sb content as the basis Antimony payment is based on a short ton unit containing 20 lbs antimony

Antimony concentrate Wogen has developed a strong position in Chrome and Manganese ores and concentrates for the international metallurgical industry Chromium is sourced from deposits in the Bushveld complex in South Africa as well as other major producers in Turkey Kazakhstan India Zimbabwe Pakistan and Oman

Mercuryantimony ores are enriched mainly by flotation yielding a mercuryantimony concentrate which is rather resistant to separation because of the similar flotation characteristics of mercury

Throughout the world there are many lead and zinc ores concentrates or by product materials which have significant value but also contain arsenic antimony tin and mercury

Yellow Pine mine was the largest source of tungsten and antimony ores in the United States from 1942 to 1944 Gold and silver ores also are taken from this mine Only gold antimony and silver ores were mined in the Meadow Creek mine which was closed in 1938 Quartz monzonite and related rocks of the Idaho batholith locally containing
