Scientists at South Australia\u2019s Flinders University<\/span> are developing a series of experiments to extract minerals from ore using environmentally friendly microbes<\/span> usually found on mine sites.<\/p>\n

Associate Professor Sarah Harmer said<\/a> the next phase of the new technique \u2013 called bio-flotation \u2013 involves larger and more complex experiments.<\/p>\n

\u201cWe\u2019re making real progress in finding better ways to more sustainably separate valuable ores such as copper, iron, lead and zinc,\u201d she said.<\/p>\n

\u201cAt the moment we\u2019re mixing together pure minerals of known quantities and purity and studying the effects.\u201d<\/p>\n

Harmer\u2019s team used high-tech x-ray imaging and micro-spectroscopic methods to study the distribution of chemical species responsible for selective attachment of bacteria and the separation of metals.<\/p>\n

They also used extreme light beams in synchrotrons to pinpoint the chemical mechanisms of bioleaching of copper ore, using soft and hard x-ray spectroscopies.<\/p>\n

Harmer said it was critical to make the technology cost effective on a larger scale for commercial use in the mining industry.<\/p>\n

\u201cThat\u2019s what has really slowed the adaption of using microbes and different types of bacteria for minerals processing. They\u2019ve only been done on a small scale in the past due to the cost,\u201d she said.<\/p>\n

She added that the new technology has the potential to replace toxic chemicals such as cyanide currently used to separate minerals from ore.<\/p>\n

Another technology is being developed as part of the EU\u2019s research and innovation program<\/p>\n

The BIOMore project<\/a>, part of the EU\u2019s research and innovation program, is developing another extraction technology aiming to extract minerals from deep deposits. The process uses both hydro-stimulation and in-situ bioleaching, which extracts metals from ores using innocuous living organisms and sulphuric acid.<\/p>\n","protected":false},"excerpt":{"rendered":"
