Bauxite residue (Red mud) is produced in alumina plants by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The global residue inventory reached an estimated 3.5 billion tons in 2014, increasing by approximately 120 million tons per annum. The appropriate management of bauxite residue is becoming a global environmental concern …

By 2013, plant's annual output was expected to be about 650,000 tonnes of alumina [7], but according to the data [10] in 2014, the Tan Rai bauxite-alumina complex churned out 485,000 tonnes, and in 2015, it is expected to produce 540,000 tonnes.
In addition to the use of grinding mills in Bauxite preparation circuits, the use of rotary drum scrubbers is finding increasing application. ... the fine bauxite from the coarse intrusions and the trommel underflow is then pumped to the downstream process plant. The intrusions are rejected as trommel overflow and conveyed to a waste dump. Fig ...
In 2001 Alcan sold its bauxite mining and alumina plants in Jamaica but kept responsibility for many of the bauxite residue sites with the intention of safely remediating them to an agreed standard and transferring ownership to the …
3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw …
The bauxite flotation processes at the Henan flotation plant and DE plant were compared. As a result, at the DE plant, cationic PAM and nonionic PAM were used for concentrate sedimentation and tailings sedimentation, respectively, and the concentrated circulating water and tailings circulating water were mixed in the circulating pool.
Mineral, Petroleum and Coal Deposits. Charles S Hutchison, in Geology of North-West Borneo, 2005. VIII.5.2 Bukit Gebong. Bauxite has been formed from gabbro on the steep-sided Bukit Gebong (334 m). The deposit was estimated to contain a mineable 1.5 Mt of washed bauxite with an average composition of 49.4% alumina (Wolfenden and Haile, 1963).The bauxite formed a …
EGA's pilot plant will use proprietary technology to convert caustic bauxite residue into an environmentally benign raw material in hours, instead of undergoing decades-long, natural processes. This Optimised Bauxite Residue is the main ingredient for a manufactured soil, which EGA calls 'Turba' (the Arabic word for soil).
The USA, ally to South Korea, needed to replenish its aluminium stockpile. This led to Reynolds constructing an alumina plant at Corpus Christie, Texas, to use Jamaican ore. The bauxite was won from mines at Lydford in St. Ann parish, transported 8 miles to the north, and exported from the Ocho Rios Port to Texas.
Bauxite is the main constituent material in the aeroplane-making industry, electric industry, machinery and civil tool-making industry. It is also used as a desiccating agent, adsorbent, …
In order to address this imbalance, three institutions were created: the Jamaica Bauxite Institute (JBI), Jamaica Bauxite Mining Ltd. (JBM) and the Bauxite and Alumina Trading Company (BATCO). Established in 1976 as an arm of the Jamaican National Investment Company, the JBI's role was to deal mainly with the sovereign aspects of the ...
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. Milling
