(a) keewatingrenville, as in the michipicoten and see full list on 911metallurgist the orebodies, consisting of hematite and limonite, with sometimes a little magnetite, have been formed by two distinct processes: 1. (a) the weathering of siderite into limonite and hematite, as at the outcrop of the original helen mine, michipicoten area2. (b) the leaching out of the silica, leaving the concentrated ore in place, as in the mesabi and other minnesota ranges and in labrador.only one deposit of the second kind has so far been found in ontario, that at loon lake, east of por see full list on 911metallurgist magnetite is found in three kinds of deposits: 1. those formed by magmatic segregationthese are to be looked for in areas of syeniteporphyry, gabbro, anorthosite, and diorite. deposits of this class are apt to be high in phosphorus, owing to the presence of apatite. titaniferous magnetite is found as concentrations from gabbro and anorthosite, sometimes in veinlike bodies, often in irregular masses. large bodies of titaniferous magnetite are found in ontario and quebec. east of rainy lake see full list on 911metallurgist limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. the limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of s, as at radnor forges, quebec. considerable deposits of limonite have been found in places where there is no standing water at present. limonite is sometimes formed in large quantities by th see full list on 911metallurgist siderite or spathic iron ore, is usually gray or whitebut at the surface it weathers to limonite, and the weathering may extend to a considerable depth. a rusty capping may cover a deposit of siderite. where the ore forms the face of a cliff, the limonite may wash away as fast as it forms, leaving the siderite clean. the ore is found in vast quantities in the iron formation of the michipicoten district, ontariothe quantity around the helen mine is estimated at not less than 100 million to see full list on 911metallurgist coal types of coal: peat, lignite, bituminous coal jan 25, 2016 · coal formation of coal types of coal peat, lignite, bituminous coal ampanthracite coal. carbon content in different types of coal. importance of each type. digging deeper: mining methods explained anglo americanthe ore body is too deep to mine profitably by open pit. the grades or quality of the orebody are high enough to cover costs. underground mining has a lower ground footprint than open pit mining. what is underground mining? the underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining.
