Tailing mining via bioleaching

CEO at SmartDry Liquefaction

Rio Maior, Portugal

About

In the EU, there are thousands of mining tailings deposits that are suitable for bioleaching and metal recovery.

We have a new technology to pre-inoculate tailings (or any other material, ores, concentrates, sludges, industrial waste, etc.) so that each grain is surrounded by the largest number of cells in minutes and using the smallest possible volume of bioleaching agent (between 15-25% w.v.). We seed the material using liquor (PLS) to ensure the best performance and we do not lose PLS.

This new process has a much lower Opex cost than classic heap bioleaching.

We are looking for tailings owners or investors to develop projects in tailings deposited in public areas.

Our purpose is to carry out environmental remediation using part of the mining revenues and return the area to a condition as close as possible to its original state.
