Apr 09, 2015 Hydrothermal ores – These are iron ore deposits formed by hot solutions which transported iron and replaced rocks of favorable chemical composition with iron minerals to form irregular ore bodies. In these deposits, iron often occurs as siderite (FeCO3) or sometimes as oxides.
The Urucum district is located in the Brazilian state of Mato Grosso do Sul near the city of Corumba on the Brazilian Bolivian border. The district comprises an area of 200 km 2, where eight up to 1,000 m high tabular mountains rise out of the swampy lowlands of the Pantanal.The tabular mountains are partly built by an up to 350 m thick rock sequence of the Santa Cruz Formation.
However, if the composition or characteristics of the cargo are variable between successive shipments for any reason, then a new TML test is required each time. 16 Unprocessed ores such as iron ore fines and nickel ore vary greatly in composition not only from shipment to shipment but also within each individual shipment. Thus, for these.
