The crushing of quartz ore began at Mathinna (E) (mine giving 246,000 ozs of gold from 300,000 tons of ore) and Tower Hill near St. Mary
1. Crushing the rock. I wish this process could be as easy as it sounds. However, if you crush the rock the wrong way, then you will end up losing some of the valuable gold. Use a bash plate and a very strong container when crushing the stone to get the gold, so that you do not lose any piece of gold.

If you are finding quartz pieces that have dark red or black attached to it, this is also a good sign that there is high iron content, and you may want to crush and sample some of the nearby rocks. I find more specimens like this one (dark with iron staining and other matrix) than I do with just gold and white quartz.

As he broke it up, he checked for gold veins and found none, but panned out the crushed rock and found what appeared to be nearly 0.5 grams of nice gold flakes.

These ores should be crushed to release the gold from the rock. These are a few close-up pictures of REAL gold in quartz specimens. Although the gold is nice, it isn’t really very showy unless it is under magnification, so these are good ones to crush… Crushing

Gold extraction. Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870. Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes

Crushing & grinding: For most of the mineral ores, due to the geological evolution, they are contained in or stick to rock veins. After mining the mineral ore is mined from underground, then the first procedure is to crush the big lump rock to small size for further processing.

An ore containing 1% S will produce a mass pull of approximately 3% by weight to a flotation concentrate. If this ore also contains 1 g/t Au (for GSR =1), and 95% recovery to concentrate is achieved then 0.95g will be recovered and with a concentration ratio of 33 (3% to concentrate) this corresponds to 32 g/t Au in concentrate.

Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.

A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenic-bearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.

In many gold ores, the majority of the gold is located in cracks and the space between the quartz crystals. This happens because gold is often deposited in the last phases of vein formation. The result is that the first crushing step will yield the most gold, with each pass after that yielding less.

Crushing and processing gold ore takes some technique, trial and error, and some patience, but you will find plenty of gold in our ore. Many customers report anywhere between half a gram to a few grams a pound and some pieces are just veined all the way through making them far more valuable as specimens than for ore processing.
