S. AFRICA'S BATEMAN USES NEW PROCESS FOR GOLD, COPPER MINING
(The following is a reformatted version of a press release issued by BATEMAN PROJECT HOLDINGS LIMITED)
Johannesburg, Sept. 9 -- A revolutionary new process which uses microwaves to unlock gold, copper and other metals from refractory or hard to recover ores is being brought to commercial production by Bateman Project Holdings (Bateman).
The microwave technology offers cost savings and more effective metal recovery at operations mining difficult and/or sulphide ore bodies. It can also make commercially viable those mineral reserves which have previously been rejected as uneconomic because of the difficulties of extraction.
The basic technology was developed in Canada by EMR Microwave Technologies. EMR has run pilot plants successfully for a number of years and has now joined forces with Bateman to commercialise the applications in minerals processing.
Both companies are excited about the prospects for the technology in the world's mining countries and are already in discussion with a number of mining houses.
The microwave technology is particularly suitable to the extraction of metals from what are known as refractory ores, or ores where those metals are not directly recoverable due to the association of other elements such as sulphur and arsenic.
Refractory gold ores are commonly encountered around the world and in 1996 produced about a quarter of the world's total gold output. In future this process could increase the recovery of gold from these ores by making them more amenable to processing.
Refractory ores are not commonly found in South Africa, except in the Barberton area which produces a small proportion of the Republic's gold.
Bateman CEO John Herselman said that the technology could have significant impact in southern Africa in the processing of ores containing platinum group and base metals and heavy mineral sands. Here the application of this technology to sulphide flotation concentrates to replace historic roasting would have huge potential.
Herselman said the EMR investment fitted in perfectly with Bateman's strategy of investing in new niche technologies in its areas of expertise which offer long term rewards. "We believe this has huge potential as part of our technology portfolio. It will enhance the group's competitive edge in acquiring future business while simultaneously being an attractive direct investment," he said. "We see a whole new suite of minerals treatment emanating from this microwave technology." said EMR president James Tranquilla. "The technology's applications were truly global and we have mining companies interested in Canada and the US, in South America, Australia, and Europe."
Tranquilla said EMR had kept the process quiet until recently to keep it away from competitors while international patents were taken out, and to investigate its further potential. "We are the only company that has this technology ready for commercial use. A conservative estimate is that we are at least three years ahead of any competitor in the development and application of these technologies in the mining industry".
The microwave process comes in at the extraction stage, when ore has been brought to the surface for treatment.
The equipment which will be required for minerals processing applications will essentially be conventional. It is easy to adapt designs to maximise the energy efficiency of the microwaves and handle the feedstocks. Microwave equipment is well proven with a long lifespan, simple to maintain and easily meets environmental safety standards.
Although it is a high-energy microwave process, it uses less electricity than other extraction methods. For example it would offer significant cost savings when preparing sulphide gold- bearing ore for cyanide leaching compared to autoclaves and roasters.
The process is also environmentally friendly in treating sulphidic refractory ores.
The combination of large reductions in both capital and operating costs means potentially very significant savings in production costs.
While this technology is not applicable to all ores, the results in difficult to extract ores can be impressive. In tests on a Mexican ore in which both gold and silver were trapped, with at least 50% of gold unrecoverable by cyanide leach, the microwave treatment resulted in close to 100% gold recovery.
The process is completely safe. The industrial use of microwave energy is in at least its third decade of worldwide application and is widely used in ceramics, pharmaceutical and chemical synthesis, glue and rubber curing and the sterilisation and incineration of hazardous materials.
The joint venture will bring commercial applications of microwave technology to the mining industry.
Bateman will provide engineering experience in establishing a much larger pilot plant than the 20 tonne per day unit on which test work has been conducted. Large mining companies have to treat up to 3000 tonnes of ore per day. "Together we will produce a practical operation which meets the requirements of the mining industry." Herselman said. "Bateman brings to the joint venture an understanding of the mining industry, while EMR contributes the knowledge of microwave technology. "We will jointly provide the technology that allows mining houses here and around the world to tackle deposits that were previously out of reach."

Headline: Microwave technology used to unlock mineral wealth
Sub Headline: Local group Bateman teams up with Canadian firm to market product locally
By: Llja Graulich
Engineering group Bateman Project Holdings (Bateman) has teamed up with Canadian company EMR Microwave Technologies to jointly market and distribute a product which could revolutionise the mining world.
The process uses microwaves to unlock gold, copper and other metals from refractory and hard ores and has proved in tests to be substantially higher yielding than other methods. It offers also more effective metal recovery at operations struggling to come to terms with extremely sulphide ore bodies.
The microwave process comes in at the extraction stage, when ore has been brought to the surface for treatment.
EMR has been running tests over a number of years and has used more than 300 different ore suites, 80% of which have been gold related, to test its product.
Bateman CEO John Herselman says his company's involvement will be to bring the product to a commercial production level and assist EMR in providing total solutions to clients.
Bateman has taken an equity stake in EMR which has also ensured the group receives the exclusive rights for the product on all mineral related usages.
While patents have been taken on the technology, Herselman says that even if other companies were to develop similar products the venture between Bateman and EMR is three to five years ahead of the pack.
Bateman has known about this technology for more than a year but had to satisfy itself that this process has "something revolutionary".
Herselman said his first reaction was that "this idea had to be too good to be true".
The company hopes to have a pilot plant up and running in SA within the next year and this will add to the interest of various mining companies.
EMR president James Tranquilla, who has more than 30 years experience in microwave technology, said that while his company had tested the technology mainly on gold related ore, its use could be spread across the whole metal range.
Herselman said he sees the main application of the microwave technology not in gold but in base metals and specifically copper. The vast copper belt in Zambia and the Congo could be ideally suited.
The product can also make commercially viable those mineral reserves previously rejected as uneconomic because of extraction difficulties.
However, Herselman said, the mining industry was known for its conservatism and he would just let things run at their natural pace.
Tranquilla said a positive for companies in times of low metal prices was that the technology was cheaper at the set up stage, but cost savings would really come to the fore at the production level.
Chucka
P.S.- the mining industry was known for its conservatism and he would just let things run at their natural pace.
Tranquilla said a positive for companies in times of low metal prices was that the technology was cheaper at the set up stage, but cost savings would really come to the fore at the production level.
P.P.S.- Oh, there are two "i" s in it! LiaisON. |
