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 ...
Ore Sampling Methods: Good & Proper. Previous Next ... For fine-grinding machines, the coffee-mill type still successfully holds its own against most of the newer devices, although the modern sample-grinder is much heavier, better built, and more easily cleaned than its predecessors. ... it would be manifestly impossible to sample such a lot of ...
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.
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 ...
Gold Ore Sample Mill. Three ore samples were selected for this studyhe first one was a refractory gold ore that consisted mainly of dolomite, quartz, albite, and muscovite, the main ore minerals being goldbearing arsenopyrite and pyritehe second sample was massive pyritebased copper ore and the third one was limestone, consisting of calcite and quartz.
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.
