The Australian gold industry has made large steps forward in the last few years. This progress has been driven by improvements in mining and processing technology, the high price of gold and by a favourable legislative, political and taxation environment. This paper concentrates on improvements in gold project development, process engineering and technology as seen by BHP Engineering, Perth, Australia._x000D_
The paper describes technical aspects of successful gold project development including metallurgical testwork, feasibility studies, choice of process flowsheet (gravity, heap leach, carbon in pulp (CIP), carbon in leach (CIL) or other routes). It sets out our views on plant design, plant construction, procurement and project management._x000D_
A case study for a small plant recently completed in the Philippines is presented as a solution to the problems often encountered in treating quartz vein gold deposits.
