Gravity Gold 2010

Description

Gravity Gold 2010 aimed to explore the issues of mining operations that are characterized by coarse-gravity gold mineralization with an often high-nugget effect. The papers from the proceedings, held on September 21-22, 2010 in Ballarat, Victoria, Australia, cover issues related to flotation; gravity concentration; leaching; metallurgical testing; selective mining and stope cleaning; plant optimization; orebody variability; safety and security; and sampling. Case studies include projects in Africa, Australia and North and South America. Content: Front Matter • Table of Contents •Part I. Keynote Addresses 1.
