Vanadinite Vanadinite Vanadinite is a mineral belonging to the apatite group of phosphates, with the chemical formula Pb(VO)Cl. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico, vanadinite deposits have since been unearthed in South America, Europe, Africa, and North America. Vanadinite is an uncommon mineral, only occurring as the result of chemical alterations to
Heavy mineral sands ore deposits in run of mine (ROM) grades as high as 86% heavy mineral concentrate (HMC). The source of heavy mineral sands is in a hardrock source within the erosional areas of a river which carries its load of sediment into the ocean, where the sediments are caught up in littoral drift or longshore drift. Rocks are occasionally eroded directly by wave action shed detritus, which is caught up in longshore drift and washed up onto beaches where the lighter minerals are winnowed. The source rocks which provide the heavy mineral sands determine the composition of the economic minerals. The source of
