Brine extraction for surface process and recovery of potash, lithium and industrial salt requires the application of traditional hydrogeological theories to hyper-saline solutions. Such Read more... about Lithium Brine Projects: there is a resource, but is there a reserve?

A major issue with the disposal of sulphide-rich mine waste is the release of acid rock drainage (ARD). Often the course of action taken is ‘end-of-pipe’ treatment, however this action is undesirable due to high cost and continued liability. The environmental problem of ARD has long been Read more... about ARD in waste rock: preventive methods

Whilst issues such as cyanide, toxic metals, arsenic and acidity are generally given the highest priority in connection with the treatment of mine waste or effluent, they are not generally the most persistent. Volumetrically dissolved salt constituents such as sulphate, sodium and calcium are Read more... about Sulphate and salt minerals: the problem of treating mine waste

Traditionally, mineral processing plants are designed to achieve the highest recovery of valuable material with limited regard for the cost of managing waste products—both solid and water components. Read more... about Reducing Water Management Risks Through Processing Changes
