The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight. [3], whereas in metal mining, stripping ratio is unitless and is expressed as weight/weight. [2] A stripping ratio can be expressed as a ratio or as a number.
Net Smelter Return (NSR) is the net revenue that the owner of a mining property receives from the sale of the mine's metal/non metal products less transportation and refining costs. As a royalty it refers to the fraction of net smelter return that a mine operator is obligated to pay the owner of the royalty agreement. The royalty is paid in ...
A company's earnings before interest, taxes, depreciation, and amortization (commonly abbreviated EBITDA, [1] pronounced / ˈ iː b ɪ t d ɑː,-b ə-, ˈ ɛ-/ [2]) is a measure of a company's profitability of the operating business only, thus before any effects of indebtedness, state-mandated payments, and costs required to maintain its asset base.
Profit margin is calculated with selling price (or revenue) taken as base times 100. It is the percentage of selling price that is turned into profit, whereas "profit percentage" or "markup" is the percentage of cost price that one gets as profit on top of cost price.
In order to perform a profitability analysis, all costs of an organisation have to be allocated to output units by using intermediate allocation steps and drivers. This process is called costing. When the costs have been allocated, they can be deducted from the revenues per output unit. The remainder shows the unit margin of a product, client ...
Mining of sulfur from a deposit at the edge of Ijen's crater lake, Indonesia. Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.
A mining feasibility study is an evaluation of a proposed mining project to determine whether the mineral resource can be mined economically. There are three types of feasibility study used in mining, order of magnitude , preliminary feasibility and detailed feasibility.
Mineral 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 used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
