"We are seeing bonanza gold grades immediately west of some artisanal workings where we identified gold in veins in September, and 100 metres further east of that, on the other side of the creek we are seeing more high grades in an intersection of 8 metres at g/t with individual samples up to 39 g/t." With multiple targets across untested ground over eight kilometres of prospective ...

(A) Ore texture defines the theoretical grade recovery curve. Particle images are used to show how high target mineral recovery will typically also mean recovery of gangue, reducing the grade. (B) If actual grade/recovery is less than the theoretical, then operational conditions may be changed to improve this (1). If grade/recovery above the theoretical curve is targeted, then the texture of ...
Cutoff Grade Theory and Practice. Consider a block of ore that weighs 1 tonne and contains 3 grams of gold. At a gold price of US1000 per ounce the value of the gold in the block of ore is just under 96 (1000/31 X 3 or 1000 per ounce/ 31 grams (troy ounce) X 3 grams of gold)
grade tonnage curve has been applied in economic and financial analysis probably being one of the most important tools used in determining the volume and grade of material in face of variations of the cutoff grade. The grade tonnage curve is usually calculated with the insitu resources or reserves and shows always the ''best'' or ''optimistic'' scenario,, at a given cutoff grade the ...

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 find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn''t available, I refer you ...
In 2012, two barges carrying highgrade gold ore presumably from Avlayakan mine, capsized and sank in the Okhotsk Sea. With remarkable g/t ore grade, this openpit mine sits first in our ranking.
The theoretical graderecovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical graderecovery can be readily used to quickly identify potential recovery ...

At a 75% gold recovery, it takes 41 tons of ore on the pad to recover one ounce of gold. However, all the material in the mine is not ore. Most mines will have 23 tons of waste material to 1 ton of ore. This waste must be taken to a separate dump. This is called the "strip ratio" and is a very important aspect in developing and operating a heap leach mine. If a mine has a 31 strip ratio ...

also proved on most typical industry cost curves: assuming everything else being equal, mines producing a higher head grade runofmine (ROM) are usually positioned in the lower quartile of the cost curve. This increased consumption, coupled with a general increase in input costs (and electricity in particular for South African mining operations), exponentially increases gold production costs ...
Gold mine exploration is challenging and complex. It requires significant time, financial resources and expertise in many disciplines – geography, geology, chemistry and engineering.

As the cutoff grade increases, so too does the average grade of the ore mined. The curves ultimately show how the average grade and tonnage of a material delivered to a certain process are dependent on the cutoff grade selected. The revenue generated by sales can be calculated by using the following equation: Where T+c is the tonnage and x+c is the average grade of the material above the cut ...
