Low grade gold and silver ore deposits are economically processed using heap leaching methods by cyanide solutions. These methods are successfully applied to ores containing 1 g Au/ton.
The average grade differed significantly between producing and undeveloped deposits. The average grade of all producing mines is 1.18 g/t Au, which is 32.6% higher than the average of all projects still in the development phase (0.89 g/t Au). This has significant implications on future gold production. In the near term, with significant ...

Feb 07, 2020· Understanding Gold Grading . All precious metals are graded by the proportion of metal in the ore. Grams per tonne of milled ore, or g/t, is the most common metric used to represent the grade of ore.
Cut-Off grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore, while material below this grade is considered to be waste. Although in a variety of units can be used, the cut-off grade is usually expressed as: g/t (grams per tonne)
The head grade for this type of low grade gold ore was found to be in the range of 0.31 g/t to 0.55 g/t where the gold was highly associated with aluminosilicate minerals. Discover the world's ...
The cut-off grade is around 0.2g/t gold. For the 2011 year Boliden's Aitik mine (within the Arctic Circle in Sweden) milled 31.5 million tonnes at a head grade of 0.24% copper, 0.16g/t gold and 2.0g/t silver. At the end of 2011 it had reserves of 710 million tonnes at a grade of 0.25% copper, 0.13g/t gold and 1.6g/t silver. Resources totalled ...
Then 20 g of pulp was used for the (IMS-117 code) ultra trace level ICP/MS AR digestion method, and four acid 0.2 g ore grade ICP -AES method (ICP-240) and for the overlimit gold the FAS-415 method of 30 g fusion Gravimetric method was used to report gold ASSAY 33.8 ppm. Laboratory standards and QA -QC is monitored by Jaxon.

There are many more low-grade gold deposits than high-grade. For every 2.5 grams per tonne (g/t) gold deposit, Mother Nature forms another 10 deposits around 1 g/t. Generally speaking, one gram per tonne works for open-pit mines, but underground gold mines require at least 2.5 g/t to be economic.
10 g/t – 50 g/t over 50 g/t Of course it is not only the grade that count since there are a lot of profitable mining operations around the world which are developing low- to medium grade ore.
