It controls two iron ore mines in Australia and Brazil, and five copper mines in Chile, Australia, and Peru. In addition to these operations, BHP Billiton manages manganese mining operations in South Africa and Australia. Established in 2004, Consolidated Minerals is a leading manganese ore producer with operations in Ghana and Australia.
MELBOURNE, Oct 18 (Reuters) The Australian government said on Friday that it will provide more than half the funds for a A$200 million ($136.60 million) solar farm being built by Alinta Energy to help power two iron ore mines in Western Australia's remote Pilbara region.

Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other PGMs.The size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.

In a bloomery, the fire doesn't get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silies from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silies into the iron metal to create wrought iron.Wrought iron is hardy and easy to work, making it perfect for creating tools.
Iron is an incredibly useful substance. It's less brittle than stone yet, compared to wood or copper, extremely strong. If properly heated, iron is also relatively easy to shape into various forms, as well as refine, using simple tools. And speaking of those tools, unlike wood, iron can handle high temperatures, allowing us to build
In 1803, William Hyde Wollaston was able to isolate palladium from other PGMs and, consequently, in 1804, he isolated rhodium from the reaction products. Wollaston dissolved platinum ore in aqua regia (a mixture of nitric and hydrochloric acids) before adding ammonium chloride and iron to obtain palladium. He then found that rhodium could be
Pour the acidandbleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments. Collect the filtered
