Porgera Gold Mine is the second largest mine in Papua New Guinea and is regarded as one of the world's top ten producing gold mines. In 2009 it produced 572,595 ounces of gold and 94,764 ounces of silver and had 2,500 employees and 500 contractors.
The EXAMPLE Gold Mine Operating Manual has been prepared to provide a practical reference for operators in the EXAMPLE Gold Mines Processing Plant. This manual contains basic information about the process and equipment used in the process. Each unit is identified by name and equipment number. The function of each unit, a process and control description, and operating information is discussed.
Whether you know it as a cost-benefit analysis or a benefit-cost analysis, performing one is critical to any project. When you perform a cost-benefit analysis, you make a comparative assessment of all the benefits you anticipate from your project and all the costs to introduce the project, perform it, and support the changes resulting from it.

Avoid top down management solutions to process problems. Encourage attitude that other groups within the organisation are responsible to service the metallurgical process plant towards obtaining production objectives. Ensure that there is adequate planning for all groups as this is a vital role to the longer term achievement of goals.
