What is the tenor of ore? - Quora
Tonnage – Refers to the total amount of metal that can be extracted from any particular ore deposit. Tonnage is calculated by taking into account the volume of the ore deposit, the grade of the ore and the tenor of the ore mineral. Syngenetic – A ...

Grade | ore deposit | Britannica
In mining: Delineation …often referred to as its grade. Grade may exhibit considerable variation throughout a deposit. Moreover, there is a certain grade below which it is not profitable to mine a mineral even though it is still present in the ore. This is called the mine cutoff grade.
Copper Mining and Processing: Processing of Copper Ores ...
The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock. The resulting …

Break Even Analysis - How to Calculate the Cut Off Grade ...
When the OPEX is known, you can calculate the mineral’s cut off grade, which is the break even grade, below which it is not economically viable to mine the ore. To find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn’t available, I refer you to the note at the bottom of this page.

What Does the Grade of a Gold Mine Refer To?
Feb 07, 2020 · Highest Grade Gold Mines in the World. The highest-grade gold mine in the world is the Fire Creek mine in Battle Mountain, Nev., according to 2015 data. With a gold ore density of 44.1 g/t, Fire Creek falls high above Macassa, the second highest grade mine at …
Ore - Wikipedia
The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, native metals such as copper, or noble metals such as gold.

Copper Ore Types: Sulfides vs. Oxides | An Investors ...
Copper sulfide ores are typically the most profitable types of copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted ...
Ore Grade - an overview | ScienceDirect Topics
Copper ores mined by open pit methods have an average grade of 0.4 wt.% Cu and those mined by underground methods have an average grade of 1 wt.% Cu (Schlesinger, King, Sole, & Davenport, 2011). The average concentration of Cu in Cu slag based on a compilation of over 70 studies is 2.5 wt.% ( Piatak, Parsons, et al., 2015 ).
Rare Earth Elements - MIT
The concentration of cerium, the most abundant rare earth, is approximately the same as that of copper although the other REEs are much rarer. However, REEs are not usually concentrated in ore deposits in amounts that can be easily or economically mined (Long, 2010).

COPPER. - USGS
Copper ores can be grouped commercially into smelting, concentrating, and leaching ores. All three kinds of ore often occur at the same mine, but the distinction holds good in a gen eral way. Smelting ores may be either pyritic, with an excess of iron, or siliceous, carrying
