Bauxite mining, which is considered as surface mining, is land extensive, noisy and dusty. Mining pits are often interspersed within small rural communities, therefore requiring companies to relocate the people and or to monetarily compensate them. An increasing concern is the loss of habitat for Jamaicas unique plant and animal species
Jan 14, 2016#0183;#32;Bauxite is a rock that is mainly composed of various minerals. Most importantly, bauxite is the primary ore for aluminum. Aluminum is a very crucial element as its uses are varied and diverse such as its usage in transportation, items, packaging, power lines, and construction.
Apart from the Nain plant, three more bauxite refineries the Jamalcoowned plant at Halse Hall in Clarendon and the Windalcorun refineries at Ewarton, St Catherine and Kirkvine in Manchester process bauxite ore in Jamaica. Bauxite mining companies make their money from prospecting, mining, refining the precious red ore and exporting it for
Impact of bauxite mining on the environment Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical
Oct 06, 2017#0183;#32;The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

Mr. Williams, personnel from the Rural Agricultural Development Authority (RADA) office in St. Elizabeth explained that certain tests have been conducted on crops in which they have ruled out diseases and insects and have pointed to the dust emanating from the bauxite mining plant located in Nain, St. Elizabeth, as the main cause of the problems affecting residents crops.
Dust pollution usually results from emission from stockpile material at the plant and from the mining and transportation of the ore. National standards applying to the mining and processing of bauxite were developed and put in place in 1996.
ment. Research on the effects of bauxite dust on crop plants has not been well documented. Quarrying of limestone may involve the blasting of rocks, creating a noise nuisance and hazards to buildings and other structures. Excavation of mine pits with earthmoving machinery increases dust, exhaust fumes and noise in the vicinity.
