A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Approximately 80 different mineral processing machines can be arranged in a flow diagram. All object parameters can be displayed on the flowsheet using an unlimited number of labels. Object parameters are stored in three detailing levels, where the ‘Essential’ level contains data required for calculation .
The first step in the sequence leading to the construction of a process plant and its use in the manufacture of a product is the conception of a process. The concept is embodied in the form of a "flow sheet". Process design then proceeds on the basis of the flow sheet chosen.
First gold produced from the underground mine was in the fourth quarter of 2004. [10] In 2005, open cut mining continued in the high-grade areas in the first half of the year, then onto the lower grade northern section of the pit from the third quarter. Open pit ore was supplemented in the processing plant by higher grade underground ore.
Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals.

Realtor.com reported the sale price per square foot was $903. Nearly 40% of 18- to 24-year-olds surveyed names New York City as the most overpriced housing market in the country.
Carlin-type gold ore from the Twin Creeks mine, Nevada, near the Getchell Mine. This is an auriferous, silicified-decalcified siltstone/mudstone from the Comus Formation (Lower Ordovician). Ore grade is about 0.20 to 0.25 ounces of gold per ton of rock. The gold mineralization is very finely disseminated: "invisible gold".
