Mining Recovery is usually a percentage estimate of insitu ore recovered after mining has taken place. It is frequently described as mining loss which is economic mineralisation that has been lost during the mining activity. Mining Dilution is the percentage of material added to the insitu ore during mining. The mineral content of the diluent material is used to recalculate the grade of ore ...

The mining recovery factor is significantly affected by the presence of discontinuity in the target gasification formation. The methodologies and results in this paper provide a convenient and fast approach to estimate the economics of a UCG plant, once the fundamental properties of the coal-bearing formation are known. 1. INTRODUCTION Underground coal gasification (UCG) is a promising clean ...

The metal recovery rate can be found in a mining company’s National Instrument 43-101 or in a similar applicable international reporting standard. Example: When you read a press release in which a mining company announces a resource of 500 million tonnes of 1% copper and a mineral recovery rate of 80% you should actually read that the company announces 500 million tonnes of (1% * 80% =) 0.8% ...

A mining recovery factor of 80% was applied for the likely practical limits of reclaim mining, accounting for losses associated with scattered waste material in the tailings, such as material used to construct bunds/walls between the ponds and the dam retaining wall on the west side. The “Old Tailings” are processed by excavation and haulage to a dry stockpile, then transferred to a wet ...
Mining recovery, mining dilution, and processing recovery. At this stage only the diamond prices and operating costs for the current year are applied. Whittle mines the pit as if the mining occurs in a single year, hence neither the discount factor, capital, nor the mining and processing schedules are applied at this stage. Ore is selected by a cash flow method that compares the cash flow that ...
Average mining recovery factor of 90% is applied based on mining methods. Minimum stope widths of 1.5m for Longhole stopes. Designed stopes with greater than 50% inferred blocks are excluded from the reported reserve. Darlot is an operating underground mine and as such all the required infrastructure is in place and operational. Minor Capital Development will be required to extract all of the ...

recovery factor 1. Measure of extraction efficiency. 2. In mining, the percentage of metal derived from an ore, or coal from a coal seam, etc. 3. In petroleum geology, the percentage of the in situ oil that is recoverable. Between 20% and 40% is common for primary recovery techniques, but enhanced recovery by use of water injection, detergents to reduce viscosity, etc., may increase the ...

15/12/2020 In all cases, confinement reduced the recovery factor of all gases. This work provides insights to devise strategies to improve the current recovery factors observed in shale reservoirs. With only less than 10% recovery, the primary production of hydrocarbon from shale reservoirs has redefined the energy equation in the world. Similar to conventional reservoirs, Enhanced Oil Recovery (EOR ...
Based on the analysis of foreign and Russian experience in the pillar cleaning-up at the boundaries of working areas and the methodical guidelines and instructions, a technological scheme was developed that allows increasing the coal mining recovery factor in the near-bottom part of the Vorkuta deposit from 0.75 to 0.9 without fundamental changing of the ventilation and transport networks and ...

A mining recovery factor of 0.95 was applied to both cut-and-fill and longhole open-stope production, with the exception of the final retreat under cutand-fill sill pillars where a mining recovery factor of 0.80 was applied. Minimum mining widths of 6 m for cutand-fill and 3 m for long-hole openstopes were used. A minimum pillar dimension between parallel stopes of 4 m for cut-and-fill and 7.5 ...
