This page represents various kinds of deals with Manganese ore.
Selling offers and purchasing requirements may both be shown on this site. As an example you may see offers of Manganese Ore in various locations, quantity and quality. Manganese mines may be found worldwide, for instance in Brazil, Mexico, Zambia, China and other countries. The offices that sell the ore may be represented at various locations. You can offer or find the ore of different quantities. It may be the single requirement of 30,000 tones (or just "large quantities") or fixed monthly need of the Manganese Ore.
In order to show the purity of the product lots of announcements have the percentage of the ore offered or needed.
A big advantage of the site is the fact that every announcement on the page is marked with a flag of the country it comes from. So it makes easier for the clients to find the most suitable location or calculate the shipping price of the product.
Together with Manganese Ore there are requirements of Manganese lumps, Zinc, Iron and other ores, so you may find some double or triple announcements.
On this page also may be located services which offer to purchase minings, for example the one in South Africa for Manganese and diamonds.
Manganese (Mn) in its pure form is a bright metal with iron-grey color and high hardness. It’s harder than iron and can scratch glass and tempered steel. Relative weight Mn - 7,4; melting point 1.260°С. Manganese is similar to iron, nickel and cobalt in its chemical properties. Manganese does not exist in nature in its native form. This natural mineral in earth’s crust included in the form of compounds with oxygen (oxides), with carbon (carbonates) and silicon (silicates). By the prevalence rate manganese occupies a significant place, although in the earth's crust its content is 56 times lower than iron content.
Manganese is a part of different mineral species (over 100), in which as manganese ore are of the greatest importance pyrolusite, manganate, brownie in psilomelane, relating to oxides. Of carbonates is important - rhodochrosite, of silicates - rhodonite. Аs usual manganese deposits are formed from several types of manganese ores. The content of Mn in manganese ores ranges from 5% to 56%, the content of iron comes to 40%, silica - to 30%, alumina - to 10%. The content of sulfur is little, less than 0.03%. Phosphorus found quite often; its content in ores fluctuates from 0.1 - to 1%. Manganese ores usually contain a lot of moisture - 10 and more per cent. Rhodonite and psilomelane in physical features are dense solid rocks; pyrolusite is usually included with soft. There is no generally accepted classification of manganese ores. The basis classification put the content of Mn and iron, while to manganese ores include ores containing Mn not less than 35% and containing iron not more than 10%. Iron-manganese ores include ores with the content of Mn from 10% to 30% and the content of iron no more than 30%. Manganese-iron ores usually include ores with the content of Mn from 5% to 10% and the content of iron more than 30%. Ores with more than 30% iron and less than 5% Mn are generally categorized as iron ores.
