Open-pit panel mining has been the normal surface method since the early 1960s. A strip or block of bauxite is exposed and mined, and then another panel is exposed. The first panel is normally refilled with waste rock. Several panels typically were open at the same time to supply the proper blend of ores to meet mill specifications.

The economy of Suriname was largely dependent upon the exports of aluminium oxide and small amounts of aluminium produced from bauxite mined in the country. However, after the departure of Alcoa, the economy depended on the exports of crude oil and gold. Suriname was ranked the 124th safest investment destination in the world in the March 2011 Euromoney Country Risk rankings.

Bauxite or 'red dirt', the raw material used in the production of aluminium, has been extracted in Jamaica by open-cast mining since 1952. In the 1960s Jamaica was the leading producer in the world and the industry expanded over the years to include four large refineries which process most of the raw bauxite into alumina before it is exported.

Bauxite mining is generally a relatively shallow, surface mining operation which removes a near surface 2-10 m layer of aluminium-rich material (Bardossy and Aleva 1990; Hickman et al. 1992). Bauxite develops over almost all types of geology but over one-third of the world's bauxite is formed on sedimentary rocks.
