Sample Testwork Not all refractory gold ores give a large recovery improvement after fine milling. Gold locked in arsenopyrite for example does not achieve the same gold recovery as gold disseminated in pyrite due to the smaller gold particle size of the locked gold (Figure 5). Figure 5. Gold Recovery of Arsenopyrite and Pyrite Ores 50 55 60 65 ...
That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich. Many mines can run profitably on much lower grade ores, which might easily reduce the average value of ore down to 25 cents or less per pound.

In the Mogollon district, New Mexico, goldsilver ore occurs in veins in a gangue of quartz, calcite, wallrock fragments, and some fluorite. According to Kidder, a grab or "scale" sample was taken from each car as the ore was trammed to the mill and a composite sample made for each shift.
A gold mill houses the equipment necessary to remove gold from the surrounding waste rock, either by concentrating it or by mechanically separating it. The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material.

It is advisable first of all to examine the ore for visible gold and silver, the presence of which might influence the choice of a method of treatment. If no gold or native silver can be seen in the rock, take a representative sample of about 300 grams and grind it up to pass a No. 30 sieve.
Among freemilling gold ores placer gold is a special case, as there is no pretreatment required for gold extraction. Gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. In modern practice, concentrators use centrifugal force in order to liberate finer gold .

Refers to the tailings abandoned row ore dressing plant, the average per ton of gold content in tailings. It is a reflection of the degree of metal loss in the process of ore .
The value of any series of experiments depends entirely upon the kind of sample of ore provided for the test. It must represent, wholly and completely, the character of the material that will be treated in the plant to be designed and constructed. If it does not, the tests will be useless or, worse, misleading. In some cases, owing to conditions under which mining is carried on, it is ...
