Lime and Limestone and Jamaica's Opportunities

Lime and Limestone: "Limestone [1317-65-3] is a naturally occurring mineral that consists principallyof calcium carbonate [471-34-1]. It generally contains some magnesium carbo-nate [546-93-0] as a secondary component. Limestone is found in many formsand is classified in terms of its origin, chemical composition, structure, andgeological formation (1). Deposits are distributed widely throughout the world.Limestone is an essential raw material for many industries, including limeproduction. Its suitability for a particular application depends profoundly onits physical and chemical properties."

Limestone is Jamica's most abundant mineral. The White Lime-stone provides the rocks most frequently used. These vary from chalky to marly beds and some contain flint nodules. Even the best of the hard limestone is usually well fractured. Apart from being essential to the production of cement, limestone is also used in building construction and as a fill in road construction. In a few localities the limestone has a beautiful pink colour but in general it is white.

Some horizons of the limestone are extremely pure and are used in the manufacture of lime. This is a major raw material in the alumina industry. Lime is also used in agriculture, sugar-refining, glass-manufacture and building.
