The effects of the disposal of copper mine tailings on the littoral meiofaunal assemblages of the Chañaral area of northern Chile were studied. Of the metals data collected, only in the case of copper was there a clear association with the tailings distribution in both the seawater and porewater samples, and it is assumed that the tailings on the beaches was the source of copper in the adjacent...

Phosphorus is an essential and non-substitutable element for the cellular processes of all living organisms. The main source phosphorus in biosphere phosphate rock. With more than 700 Mt rock, Estonia holds largest sedimentary rock deposits European Union. Estonian particularly outstanding due to its remarkably low content hazardous heavy metals such as Cadmium (<5 ppm) trace elements Uraniu...

The mining industry has seen a significant decline in mill feed grade recent years, resulting an ongoing build-up of materials not recovered at the mineral processing plants whose economic value yet been determined. Tailings dams have preferred method disposal such materials. However, dam breach events and growing demand for goods enhanced appeal more effective use mined to prevent tailings acc...

In this research study, we focus on the tree test results as well first-order kinetic model to evaluate flotation data propose a conceptual design of circuit for specific coal sample. Results from showed it was possible achieve product with ash content less than 10% 8% combustible recovery and indicated sample, obtain low – condition. Kinetic some streams had same constant, so could combine sim...
