When the preliminary feasibility study of a mineral project has not been completed yet, but you do want to estimate the mineral deposit value, you can calculate the potential value of a mining project by the back-of-the-envelope calculation described in this article.

The standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock to find the tonnage.

Estimates of the tonnage and average grade of ore deposits (ore-reserve estimates) are made for various purposes. They may be made by examining engineers as a basis for placing a value on a mining property in connection with reports on behalf of owners or vendors, on the one hand, or for prospective purchasers or lessees, on the other.

Mineral resource estimation. Jump to navigation Jump to search. Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods (see below) used for different scenarios

this is the practicality of the mining and processing methods proposed for the deposit. Best practice includes the use of peer reviews to test various aspects of the Mineral Reserve estimate including the inputs, methodology, underlying assumptions, the results of

Lane’s Method. Lane's Method was presented by Ken Lane in 1988 when he identified three distinct stages of cut-off grade application; mining, concentrating, and processing. He related these steps to the concept of Net Present Value to create a method of cut-off

tonnage calculation in mineral processing phonechecker.co.za. calculate gpm water to ton of processing ore. 1.1 PHASES OF A MINING PROJECT . There are different phases of a mining project, beginning with mineral ore exploration and ending with the post-closure period.

In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock.

Therefore, amortization tonnage can be expressed as a function of mining rate. The amortization tonnage is calculated for a series of mining rates, one of which will indicate a minimum tonnage. Part II describes a procedure for calculating the optimum mining rate to obtain maximum present value of an ore body, when mining rate is the only variable.

For the calculation of the volume and the tonnage of ore deposits there is a variety of available methods to choose from, each suited for a particular deposit. These methods fall into two categories:...

grade tonnage curve in mining overlandconnection. mining where the ore grade is highly variable and by selecting out only high grade areas to mine a reduction in cost can be,of the MMD grade tonnage curves would be the mining method and the grade

The issue of balancing dilution and ore recovery is a challenging one as profitability is to be optimized while not effecting the efficiency of operation. It has been noted that instead of utilizing labour intensive mining methods to high tonnage bulk mining has decreased the ability to control ore recovery.

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order- of-magnitude estimates.

method is not a widely appreciated or applied approach to maximizing the value of a mining operation through selection and balancing of operational cut-off grades. Three stages in a mining operation, namely mining, processing and marketing were defined by Lane and the economics of each stage are identified and isolated

31-12-2019· In extraction and mining industry, entities have fixed assets mines, quarries and wells to extract natural resources like coal, oil, timber, metal, salt etc. Unlike property, plant and equipment that are used during the period, these assets get consumed as a result of extraction.
