With the intention to open up the possibility <strong>for</strong> an economic evaluation <strong>of</strong><br />

presented hydrometallurgical <strong>process</strong>ing route, the techno-economical assessment is<br />

achieved through the development <strong>of</strong> gold amount variation models, present in waste<br />
