This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz - gold bearing veins can consist of calcite or mostly sulfides - which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.

The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell. The refiners will then pass an electric current through the cell. At the end of this process, the gold will be 99.99 percent pure. Reclaiming the Mine No gold mine lasts forever.

Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.

Check the tailing piles and waste rock near the entrance of mine openings. Remember that gold miners didn't have metal detectors hundreds of years ago, so it was easy to overlook gold that was peeking out of a piece of quartz. Another interesting thing to consider is that back then it took a lot of gold to be worth the effort to process.

Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

The gold was brought to the surface as small particles embedded in lumps of quartz. The quartz was then crushed into a fine dust by stamping batteries in a stamp mill. A stamp battery contained a row of stamps. On the bottom of each stamp was a heavy piece of iron steel. Each battery was driven by a cam shaft which was turned by a water wheel.

Waihī. Gold was discovered at Martha hill, Waihī, in 1878, but ore grades were low. The cyanide process, which made mining profitable, turned Waihī into one of the great gold-mining districts of the world by 1900. Waihī was a bustling town of 5,600 residents in 1906, larger than Thames and overshadowing Hamilton's 2,000.
