The University of Queensland has worked with Rio Tinto to create a new way to process bauxite ores.<\/p>\n

According to the university, not only does the method add value to the ore, it also reduces the mine\u2019s environmental footprint.<\/p>\n

UQ\u2019s Dr. Hong Peng, from the university\u2019s School of Chemical Engineering, said the process utilises bauxite ore waste.<\/p>\n

\u201cQueensland is ideally placed to benefit from this technological improvement as bauxite is abundant in north Queensland and there are already processing facilities and experts established here,\u201d Peng said.<\/p>\n

\u201cNow instead of wasting the bauxite ore by-products, we can recover most of the minerals, which also reduces the environmental impact of the mining activity.\u201d<\/p>\n

The new method will also make some previously uneconomical mines viable.<\/p>\n

Bauxite contains between 30 and 54 per cent alumina<\/span>, which is refined from bauxite ore using the\u00a0Bayer process, which separates alumina from the mixture of\u00a0various\u00a0iron oxides,\u00a0titanium dioxide\u00a0and aluminosilicate, which is known as the desilication product (DSP).<\/p>\n

Using the conventional Bayer process, the DSP crystallises to a fine powder intermingled through the residue, making separation of the components impossible.<\/p>\n

\u201cThe red mud has to be chemically neutralised and maintained in long-term storage,\u201d Peng said.<\/p>\n

Peng\u2019s method looks to control this crystallisation, instead yielding a coarser material, which can be separated and removed.<\/p>\n

\u201cThe current process wastes a lot of these other minerals and creates bauxite residue,\u201d he said.<\/p>\n

\u201cThe new method we\u2019re developing has environmental benefits and financial benefits, as the by-products can be sold.\u201d<\/p>\n

The research was supported by the Advance Queensland Research Fellowship<\/a>, which is focused on aiding the mining industry in overcoming challenges.<\/p>\n

Peng was one recipient, along with Dr. Pradeep Shukla \u2013 who is aiming to upscale new technology to produce cyanide on-site for gold and base metal mines \u2013 and Dr. Sergio-Andres Galindo-Torres, who aims to introduce new\u00a0modelling and visualisation technologies<\/p>\n","protected":false},"excerpt":{"rendered":"
