Break Even AnalysisHow to Calculate the Cut Off Grade

For conducting a mining project s break even analysis you first need to know about the operational expenses (OPEX).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

Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth shape size and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure 20.1). Creating a giant hole in the ground is generally cheaper than making an underground mine but it is also less

If the copper grade in the ore is reduced to 1 the heap height was 9 m for all the copper prices but the leaching times decreased (and also the recoveries) as the metal price increased. This simple example shows that there are clear ways to improve the design and planning in order to maximize profits in heap leaching systems.
