What Is a Stripping Ratio? with picture
16.09.2020& 0183;& 32;Stripping ratio is a term that is derived from the mining industry and is used in reference to the open-pit mining process. The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process. In relation to its appli ion in the mining of ore the utility of the stripping ratio is the determination of the approximate ratio of

US4840710A - Method of stripping electrolytically
Electrolytically deposited copper is stripped from a hode by first flexing the hode to cause at least part of the copper deposit to separate from the hode and then wedge-stripping or gas-blasting the remainder of the copper from the hode. Perferably the hode is a stainless steel sheet and flexing is achieved by means of hydraulic arms which press the center of the sheet first

Mining Methods and Equipment - School of Mechanical
The majority of open pit mines in Australia currently operate using discontinuous shovel/truck systems. These systems are favoured as they enable; i mining capacity to be progressively scaled up over the life of a mine; ii the use of narrow benches that defer the high costs of stripping and iii flexibility to rapidly adapt mine plans in the face of uncertainties caused by changing

Stripping ratio - Wikipedia
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. Stripping ratios are typically reduced to show the volume of waste removal required to extract one unit

Surface mining - Wikipedia
The method evolved from auger mining but does not meet the definition of surface mining since it does not involve the removal of overburden to expose the coal seam. CERB final report No. 2014-004 "Highwall Mining: Design Methodology Safety and Suitability" by Yi Luo characterizes it as a "relatively new semi-surface and semi-underground coal mining method that evolved from auger mining". 11

Strip Mining - an overview ScienceDirect Topics
Strip mining for copper for example produces large quantities of tailings that often contain concentrations of 100 to < 10000 mg kg –1 of such metals as arsenic cadmium and lead. Similarly iron pyrites FeS 2 which are often associated with copper silver and lead ores can have a devastating impact on the aquatic environment because their oxidation releases sulfuric acid into
