Mining Bacteria with Midas touch for efficient gold processing
Special nugget-producing bacteria may hold the key to more efficient processing of gold ore, mine tailings and recycled electronics, as well as aid in exploration for new deposits, University of Adelaide research has shown.
For more than 10 years, University of Adelaide researchers have been investigating the role of microorganisms in gold transformation. In the Earths surface, gold can be dissolved, dispersed and reconcentrated into nuggets. This epic journey is called the biogeochemical cycle of gold.
Now they have shown for the first time, just how long this biogeochemical cycle takes and they hope to make to it even faster in the future.
Primary gold is produced under high pressures and temperatures deep below the Earths surface and is mined, nowadays, from very large primary deposits, such as at the Superpit in Kalgoorlie, says Dr Frank Reith, Australian Research Council Future Fellow in the University of Adelaides School of Biological Sciences, and Visiting Fellow at CSIRO Land and Water at Waite.
In the natural environment, primary gold makes its way into soils, sediments and waterways through biogeochemical weathering and eventually ends up in the ocean. On the way bacteria can dissolve and re-concentrate gold -- this process removes most of the silver and forms gold nuggets.
Colloidal gold Uses By using colloidal gold regularly, you are able to reduce joint pains, increase the strength of your immune system, gain a sense of euphoria, reduce depression, combat fatigue, and improve circulation in your body. A research by the University of California in 1996 has also shown that usage of colloidal gold has of your body.
These results have surprised us, and lead the way for many interesting applications such as optimising the processes for gold extraction from ore and re-processing old tailings or recycled electronics, which isnt currently economically viable.
Working with John and Johno Parsons Prophet Gold Mine, Queensland, Professor Gordon Southam University of Queensland and Dr Geert Cornelis formerly of the CSIRO, Dr Reith and postdoctoral researcher Dr Jeremiah Shuster analysed numerous gold grains collected from West Coast Creek using high-resolution electron-microscopy.
Published in the journal Chemical Geology, they showed that five episodes of gold biogeochemical cycling had occurred on each gold grain. Each episode was estimated to take between 3.5 and 11.7 years -- a total of under 18 to almost 60 years to form the secondary gold.
Once liberated by the oxidation process, the gold is then available for cyanide leaching. During the oxidation process it has been found that a portion of the liberated gold becomes suspended in the liquid phase in what appears to be a colloidal state.
Dr. Abrams et.al. conducted two clinical trials on the effectiveness of colloidal gold on rheumatoid arthritis Colloidal Gold in the Treatment of Rheumatoid Arthritis RA, and Management of Rheumatoid Arthritis Rationale for the Use of Colloidal Gold. The results showed that in 8 out of 10 patients with longstanding erosive RA, colloidal gold was a fast acting less than 1 week therapy that reduced joint

Clinical evaluation of a rapid colloidal gold immunochromatography assay for SARS-Cov-2 IgMIgG
Background Since December 2019, there had been an outbreak of COVID-19 in Wuhan, China. At present, diagnosis COVID-19 were based on real-time RT-PCR, which have to be performed in biosafe laboratory and is unsatisfactory for suspect case screening. Therefore, there is an urgent need for rapid diagnostic test for COVID-19.
Objective To evaluate the diagnostic performance and clinical utility of the colloidal gold immunochromatography assay for SARS-Cov-2 specific IgMIgG anti-body detection in suspected COVID-19 cases.
Results The immunochromatography assay test had 69 positive result in the 97 PCR-positive cases, achieving sensitivity 71.1 95 CI 0.609-0.797, and had 2 positive result in the 53 PCR-negative cases, achieving specificity 96.2 95 CI 0.859-0.993. In 26 healthy donor blood samples, the immunochromatography assay had 0 positive result. In subgroup analysis, the sensitivity was significantly higher in patients with symptoms more than 14 days 95.2 95 CI 0.741-0.998 and patients with severe clinical condition 86.0 95 CI 0.640-0.970.
Conclusions The colloidal gold immunochromatography assay for SARS-Cov-2 specific IgMIgG anti-body had 71.1 sensitivity and 96.2 specificity in this population, showing the potential for a useful rapid diagnosis test for COVID-19. Further investigations should be done to evaluate this assay in variety of clinical settings and populations.
