Estimation of Open Cut Mining Recovery and Mining Dilution ...
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 ...
recovery factor | Encyclopedia.com
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 ...
Extraction of petroleum - Wikipedia
Recovery factor during the primary recovery stage is typically 5-15%. [2] While the underground pressure in the oil reservoir is sufficient to force the oil (along with some associated gas) to the surface, all that is necessary is to place a complex arrangement of valves (the Christmas tree ) on the well head to connect the well to a pipeline network for storage and processing.

Ore Dilution & Recovery in Mining
Top slicing permits high recovery of ore with little dilution (provided a suitable mat is maintained) under conditions where any method of mining from the bottom upward would be difficult, hazardous, and costly. Small stubs of ore between the ends of slices or between the end of a slice and the cave are sometimes lost, and 2 or 3 feet of ore may have to be left around the margins of a deposit ...
Metal Recovery Rate - How to Interpreted the …
The metal recovery rate, or also known as the mineral recovery percentage, indicates what percentage of valuable metals are expected to be available for sale after the refining process has taken place.The metal recovery rate can be found in a mining company’s National Instrument 43-101 or in a similar applicable international reporting standard.
ore dilution and ore recovery - LinkedIn SlideShare
Ore Dilution & Recovery in Mining Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ...

Predicting hydrocarbon recovery - AAPG Wiki
Narrow the recovery factor range by predicting the thickness of the reservoir by port type. Port type affects recovery rate. For example, in a reservoir with strong water drive and macroporosity, recovery will be up to 60%, mesoporosity recovery will be up to 20%, and microporosity recovery will be 0%. Recovery factors for different drive types. The table below shows recovery factor ...

Hence, the recovery potential must account for its efficiency and losses: (3) R e c o v e r y P o t e n t i a l T o t a l = U r b a n m i n i n g p o t e n t i a l T o t a l × R e c o v e r y E f f i c i e n c y (4) Where R e c o v e r y E f f i c i e n c y = 1 − L R e c o v e r y L Recovery denotes the loss factor associated with the urban mining exercise to recover any item and/or material.
Definition of Recovery factor (coal)
Recovery factor (coal) -- The percentage of total tons of coal estimated to be recoverable from a given area in relation to the total tonnage estimated to be in the demonstrated reserve base.The estimated recovery factors for the demonstrated reserve base generally are 50 percent for underground mining methods and 80 percent for surface mining methods.
Water alternating gas incremental recovery factor ...
Water alternating gas (WAG) injection process is a proven enhanced oil recovery (EOR) technology with many successful field applications around the world. WAG pilot projects demonstrate that WAG incremental recovery factor typically ranges from 5 to 10% of original oil in place, though up to 20% has been observed in some fields. Despite its proven success, WAG application growth has been very ...
Production-Sharing Agreements: An Economic Analysis
for cost recovery. The remainder of the production, so called profit oil, is then shared between government and FOC at a stipulated share (e.g. 65 percent for the government and 35 percent for the FOC). The contractor then has to pay income tax on its share of profit oil. Over time PSAs have changed substantially and today they
