What is the history of bauxite?
Discovery and Production Bauxite was first mined in Arkansas as an ore of metallic aluminum in 1896, only nine years after John C. Branner, the state geologist, first identified it in a sample from Pulaski County. During the twentieth century, Arkansas provided about ninety percent of all domestic tonnage mined.

Does Guyana still produce bauxite?
Guyana’s mines yield a high quality calcined bauxite, with uses in the refractory, abrasive and chemical markets for high temperature applications. Guyana’s reserves of bauxite was known to be 350-million-tons.
Which country has the best bauxite?
1. Guinea: With an estimated bauxite ore reserve of 7.4 Bnt, mostly concentrated in the western and central part of the country, Guinea stands as the number one bauxite producing country of the world. The country accounts for 26.9% of the global total reserve of the ore.
Is bauxite harmful to humans?
Exposure of this substance may give an adverse effect to those who suffer from eczema skin, heart problems and liver problems. Moreover, the content of reactive silica in bauxite is 1-8 percent. Exposure to high concentrations can cause shortness of breath, chest pain, fatigue, fainting or even death.
How does bauxite mining affect the air?
The processes of excavating, removal of top soil and vegetation, transportation of bauxite and unwanted elements and stockpiling of bauxite cause degradation of air quality mainly related to dust pollution. Dust is a solid particulate matter, in the size range of 1 to 75 microns in diameter.

Why was bauxite important in WW2?
In the early stages of World War II, merchant freighters carrying bauxite to the United States suffered major losses to enemy submarines. The tonnage of bauxite mined in Arkansas quickly increased to meet wartime demands for aluminum, which was especially critical to the military aircraft industry.
What happened to the bauxite industry in the sixties?
Examples of this have occurred on several occasions within the bauxite industry itself, during the sixties when more militant workers in some plants broke ranks with the Manley leadership of the NWU over issues of company racism and worker-employer relations in the mines and refineries.
