Different Types of Iron Ore

Oct 05, 2016· Limonite is sometimes formed in large quantities by the weathering of the sulphides of iron; such gossan has occasionally been used as an iron ore. At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore; this gossan capping of the pyrite was from eight to fifteen feet deep.

Nickel Statistics and Information - USGS.gov

The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8 ].

stone limonite ores were well adapted for use in charcoal furnaces and had been mined for that purpose since the late 1700s. Geologically, the work of Holden and other geologists of a century or more ago is impressive. They very accu- rately recognized the importance of stratigraphy and struc- ture in controlling the formation of the limonite ores.

Limonite or brown ore mining primarily involved surface methods, beginning with hand mining, and later shifting to power shovels, drag-lines, loaders and bulldozers. Ores were selectively mined for higher grade material. Beneficiation was done with log washers, mechanical jigs, heavy media separation, and in some cases, hand cobbing. ...

Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. Silicate type (or saprolite type) nickel ore formed beneath the limonite ...
