Apr 25, 2017· Aluminum is one of the lightest metals in the world and as a result it is used widely in the production of multiple product. This metal has a shiny silver color and it is malleable meaning it can be bend without breaking. In nature, aluminum is found in an ore called ore is refined using various techniques to produces aluminum oxide which is called alumina.
The first mine opened at Jarrahdale in 1963, sending ore by rail to the Kwinana Refinery. Most Australian bauxite is lateritic, formed by intense weathering of various rock formations. The alumina in lateritic bauxite is mainly in the form of gibbsite, as aluminium oxide trihydrate.
Upon reaching Canada the Bauxite ships had to navigate up the St, Laurence River and then the Saguenay River to Port Alfred where they were unloaded. The Bauxite ore was then moved to Arvida where it was processed into aluminum. The big question that leaps to mind is why move the Bauxite to Canada for conversion into aluminum.

Passenger trains may have between two and eight cars, depending upon the location and country. At the other extreme are the coal trains of Australia which can easily carry in excess of forty cars.
With a relatively simple online search ( 'how is bauxite transported') you learn that bauxite is most commonly transported by ships or trains. You carry out further online research, and check transport routes and map locations (using Google Maps or Google Earth) to map out deepwater seaports.

Profile First Bauxite MORE. First Bauxite Corp. is a natural resource company, which engages in the exploration and development of bauxite deposits in Guyana and South America. It intends to produce and sell bauxite raw ore and sintered refractory products for the refractory and energy industries.
occurs in the form of hydrated oxides or silicates (clays). The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France where the ore was originally discovered. Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America,
