INTRODUCTION
IPEX is focussed on the development and improvement of innovative hydrometallurgical technologies used by X GROUP:
-
Refinement of platform technology to expand potential fields of IX application
-
Recovery of metal values from low grade resources such as vanadium calcine tailings for conversion into premium products of high purity
-
Conversion of salts from AMD into nitrogenous compounds and purified water
TECHNOLOGY AND PLANT PERFORMANCE
The IPEX calcine reprocessing technology has been proven at commercial scales at Wapadskloof on Transvaal Alloys tailings. ENVEX is rendering tolling services on the calcine tailings of a major primary vanadium producer in South Africa. Typical project timelines are:
-
Site establishment and plant construction within three months
-
Regular product delivery within one month of commissioning
-
Steady state within three months
-
Average plant availability above 98%
Three Stage Ion Exchange Plant
