Low grade ores are usually uneconomic to mine and process, but high grade ores have a high enough metal content to be worth mining and extracting the metal. The metal ore, a mineral or mixture of minerals from which economically viable amounts of metal can be extracted, its got to have enough of the metal, or one of its compounds, in it to be worth digging out!

These innovations make it possible to mine lower grade ores and complex mineralogy, creating a safer and more productive environment, with lower operating costs. Remotely operated machinery Swarm robotics will be the next generation of mining, and will ultimately mean the removal of people from safety risk exposure, while upskilling employees in new technologies and approaches.

Cyanide Use in Gold Mining

Cyanide Use in Gold Mining

+

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;

lowgrade ore and mine waste containing nonferrous metals [2–6]. Introduction of this technology will facilitate stepbystep transition to a circular economy during the implementation of the closed procedures for solution circulation and waste material disposal in construction industry [7–9].

Gold grade

Gold grade

+

The grade of gold, and composition of the ore that can be practically excavated, are different for openpit and underground mines. The grams per tonne for a low grade openpit is then different for underground mining. Technically speaking, the highest grade of gold would be nuggets, which are some of the only naturally occurring deposits of gold.

 · Moreover, mines are expected to last a certain number of years, to pay off their capital costs, and return capital to shareholders. By setting cutoff grade too low, what was ore is now reclassified as waste and tonnage evaporates. Hence the mine life is shortened leaving someone, or everyone out of pocket.

Dealing with lowgrade ore – Process productivity

Dealing with lowgrade ore – Process productivity

+

Mining, handling and processing lowgrade ore in mining and mineral processing operations is resulting in higher costs and lower profits. While this is a widely acknowledged issue, solutions have so far been limited. New technologies now being developed are giving operators options to divert lowgrade ore at multiple stages of their operation.

The Second Law of Thermodynamics and Low Grade Mineral Ores

The Second Law of Thermodynamics and Low Grade Mineral Ores

+

These calculations are motivated by the claim by various writers (I'll get the references) that civilization is dependent on high grade ores which will be soon exhausted, and the extraction of minerals from low grade ores is limited by energy costs of separating the ore from rock required by the second law of thermodynamics. The claim is mistaken.
