If you want to learn about our products , please call or write mail consultation.

The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines

Mining and Refining Process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production. The process stages are: 1

5.1.2 Mining method selection. The selection of a mining method is the process of choosing a suitable mining technique which is technically feasible for the ore-body geometry and the ground conditions and which presents the least difficulties (Ataei, Jamshidi, Sereshki, & Jalali, 2008). The main objective of this process is maximising the

processing method. The Bayer process consists of digesting bauxite ore by washing with a hot solution of sodium hydroxide (NaOH), at 175 C and high pressure to convert the aluminium oxide content into soluble sodium aluminates (NaAlO 2) [17]. The sintering process is used for bauxite ores that are hardly digestible with the Bayer process

Oct 15, 2020 The methods used in mining bauxite differ somewhat in different countries and with different types of deposits. In deposits occurring in the form of extensive surface blankets or in beds and lenses interlayered with unconsolidated sediments, such as are being mined in Arkansas and in northern South America, quarrying is a common method of mining

Jun 13, 2014 The Chemistry and Processing of Jamaican Bauxite. The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal

What is bauxite mining used for? – AnswersToAll

Apr 28, 2021 What is the usual method of mining bauxite? Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Is aluminum foil bad for environment?
