Limestone sand has come into wide use in the treatment of waters acidified by acid rain or acid mine drainage. The direct application of high-calcium limestone sand (Figure 1) to acidified streams results in increased water pH and alkalinity. Annual replenishment is usually all that is required to maintain favorable water quality.

Lydford Mining, a company that mines and processes high purity limestone products, was established in 1991 in St. Ann Parish, Jamaica. "It was founded by Dr. Vincent Hill and Leo Cousins," says Edgar Cousins, Leo's son and the company's present Director.

Limestone Mining Methods Today, as in the past, the most demanding task of limestone mining was the cutting and lifting of the blocks of stone out of the ground, then hauling them to the mill. As has been said, it was not just the high quality of the limestone that developed the industry here, but the rock was close to the surface.

Due to the presence of other calcium products in the limestone chips typically used it is quite possible for limestone to exert alakline influenes on the wastewater stream up to an beyond a pH of 11.0, meaning that an upper pH limit of 9.0 cannot be guaranteed and can easily be violated. The pH neutralization process occurs as strong acids ...

The proposed expansion would entail the excavation of two new limestone quarry pits. In addition to wetlands, about 1.2 miles of stream channel, 1.4 miles of jurisdictional ditches and 1.07 acres of open water ponds would also be impacted.

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...

Limestone is a sedimentary rock. It forms predominantly on the sea floor where material rich in calcium carbonate ('calcareous' material) accumulates. This calcareous material may be organic, chemical or detrital in origin. The sediment that goes to make up limestone may have been derived from the dead remains of marine organisms such as:
