Jamaica - Economy | Britannica.com

Jamaica - Jamaica - Economy: Jamaica's economy is mixed but increasingly based on services, notably tourism and finance. Since independence in 1962, the country has developed markedly but unevenly. Mining and manufacturing became more important to the economy in the latter part of the 20th century, while the export of agricultural commodities declined.

Bauxite tailings - Wikipedia

Bauxite tailings, also known as red mud, red sludge, bauxite residue, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).

"Kaiser Bauxite Company" is a occurrence deposit site in Saint Ann, Jamaica. It is a deposit, not considered to be of world-class significance. 1. Aluminum deposits are documented at "Kaiser Bauxite Company." Aluminum is present at a grade sufficient to have a strong effect on the economics of an excavation project.

The Chemistry and Processing of Jamaican Bauxite

In October, 1943, Alcan was incorporated under the name Jamaica Bauxites Limited as a Jamaican company to investigate the commercial potential of Jamaican bauxite. In the same year, 2500 tonnes of ore was shipped to the USA for process investigation and it was realised that the bauxite was suitable for processing using Bayer technology.

Abstract: PHOSPHORUS MINERALOGY OF THE JAMAICA BAUXITE ...

The Jamaican bauxite ores contain the highest phosphorus amounts of any bauxite ores in the world, and samples examined for this study contained up to 32% P 2 O 5. Because apatite was thought by some to contain much of the phosphorus in Jamaican bauxites, a cathodoluminescence (CL) microscopy was initiated to examine the character of the ...

quality issues. They also face bauxite availability issues from a single source. Due to this, it has become imperative that bauxites from multiple sources need to be processed. Since these bauxites have different levels of silica and phosphate, adjustment in process conditions is a necessity to control silica and phosphate impacts.

Bauxite Mining and the Environment - AZoM.com

Jul 20, 2002· The conservation of rain forests is a key concern often voiced with regard to bauxite mining. Only about 6 % of the world's bauxite mining is today conducted in rain forest regions, affecting a total area of around 1.5 km 2 per year. The total area of the globe currently covered by rain forest is about 18 million km 2.. The original flora and fauna of much of the land involved in bauxite ...

Aluminium - Maaden | Saudi Arabian Mining Company

In 2009, Ma'aden established a joint venture with Alcoa, the world's third-largest aluminium producer, to build the world's most efficiently integrated aluminium project in Saudi Arabia. This USD 10.8 billion (over SAR 40 billion) project includes a bauxite mine, a refinery, a smelter and one of the world's most advanced rolling mills.

The dissolution of phosphorus from Jamaican bauxites under ...

In order to manage soluble phosphate in refineries that process Jamaican high‑phosphorus bauxites there is need for a simple mechanism to estimate the Ca dosages required to precipitate the PO 4 3−.Routine analytical methods for determining caustic soluble PO 4 3− are tedious and time consuming and so a relationship that predicts dissolved PO 4 3− concentrations directly from bauxite ...

Mining and Refining – Process - bauxite.world-aluminium.org

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
