Gold mining in the Overberg: fears relieved for now
A wine-maker from the area, Jack Bruce, is more pessimistic — he cites statistics that nearly 90% of exploration licences result in mining licences, and says that because gold grades in the area are so low, a huge open-cast mine of about 300ha would be needed to make the deposit pay.

The list of commodities is extensive, although the relative proportions mined underground and on the surface vary from mineral to mineral. Massive tonnages of hard coal and lignite are also produced from surface mines, although the terminology used – open cast or open cut, rather than open-pit – indicates that the technology and engineering concepts used …
Process Control in Investment Casting
Importance of Process Control Why is Process Control so important in investment casting? • There are many steps in the investment casting process. • The result of each step is highly dependent on the quality from the preceding step. KOV's from preceding step may be KIV's in next step. • Feedback from some operations can be significantly

7.2.1: Open Pit Mining | GEOG 000
7.2.1: Open Pit Mining. Open pit mining almost always applies to non-coal materials, mostly metal and aggregate mining. However, near-surface steeply dipping coal seams are extracted using open pit mining. Reclamation, i.e., returning the land to an acceptable standard of productive use of the open pit mine is deferred until the mine closes.

We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution.
