Abstract
Continuous production of bacteria for leaching metallic ore is carried out by inoculating the bacteria on a pitted plate, supplying a nutrient substrate to the bacteria to promote growth of the bacteria, periodically harvesting bacteria from the plate and conveying the harvested bacteria by sluice to a leaching site. Harvesting is preferably carried out by passing a blade over the plate to shear off bacteria above the surface of the plate leaving behind bacteria within the pits of the plate for continued bacteria growth.
Claims6
A process for the production of bacteria suitable for the leaching of metallic ore comprising the steps of:
- innoculating a pitted plate with a bacteria adapted to the leaching of metallic ore,
- supplying a nutrient substrate to the bacteria sufficient to promote abundant growth of the bacteria desired,
- periodically harvesting the bacterial growth extending above the pitted plate by passing a blade over the plate to shear off and collect the bacterial growth above the surface of the plate leaving behind the bacteria within the pits of the pitted plate, and,
- conveying the products by sluice to the leaching site.
