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. Therefore it is better to use gram-meters instead of only looking at the grade when comparing the drill results of different companies.

However, in some cases low-grade copper oxide ores can still be economically mined because they can be processed at a lower cost than copper sulfide ores. …

The high-grade players. According to Champion Iron, Brazil dominates the high-grade market, followed by Canada. Australia, Sweden, Russia, Ukraine and South Africa all produce small quantities of high-grade iron ore, but collectively they produce less than 100 million tonnes — which equates to not much more than half of Fortescue's production.

For example, high-grade copper ores, which contain a high percentage of copper, are becoming harder to find and mine. ... plants are grown in soil that contains low grade ore;

In addition, it is revealed that low-grade iron ore with a high pore properties, α-FeOOH content, and gangue content can be upgraded to a high-grade iron ore with a low pore property (low specific surface area and pore volume), high Fe 2 O 3 content, and low gangue content using the above method. Therefore, this method is promising as a method ...

Indeed, the high cost of processing extremely low-grade gold ore may actually make mining financially unfeasible. There are other key factors besides the grade of gold ore that contributes to mining feasibility. The depth of the ore deposits, and the composition of the ore, will also affect whether a …

(Table 1: Changes in ore deposit when deposit is high graded) In conclusion, high grading a deposit will result in reduced per ounce costs and improved economics; therefore, if companies cannot reduce costs they will be forced to selectively mine the high grade parts of their ore bodies.
