Yava Technologies

Over the last decade Yava Technologies Inc. (Yava) has been involved in an intensive R&D program at a cost of approximately CDN $15 million and as a result has developed a series of low cost, award winning, environmentally friendly processes for the recovery of a range of metals including: gold, silver, lead and zinc. Yava has also received signifi... cant assistance from the federal government of Canada to aid in the development of its technologies. Yava is attracting growing interest from mining companies and other industries because its technologies potentially eliminate the need for concentrating, smelting and traditional refining. As a result, profits may be increased by: a) potential lower capital and operating costs and b) the possibility of producing a value added product on site that could be shipped directly to the end user for additional profits. For example, lead could potentially be recovered as lead oxide, a product that receives an approximate 10% premium over lead metal prices. Gold and silver are recovered separately as metal. Yava has demonstrated at lab scale that its processes for lead and zinc can extract these metals as high purity, value added industrial products. Yavas zinc/lead technologies are currently being modified to recover additional metals including gold, silver, copper, nickel, cobalt, manganese, molybdenum and iron. A process to remove arsenic and certain other contaminants is also being patented along with a new technology for the production of lithium ion battery materials. At the present time Yava is working with a number of mining companies with gold, silver, lead and zinc deposits. In addition, Yava is working with a major US industrial corporation designing a system to extract valuable metals from the waste stream of a number of their plants. The Yava process is a hydrometallurgical system that recovers the metals directly from ground head ore or certain waste streams. Yava can profitably recover lower concentrations of metals and this should increase the size of a mineral ...Read More
