Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
Heap leaching operations at the Valley Leach Facility VLF have been in continuous operation since 1994 The VLF was originally designed with 6 m 2 of lined area and one internal pregnant
·valley fill leach pads now use composite liners above the maximum water storage level and double geomembrane liners below that level Single geomembrane liners are still the most common liners for copper leach pads with composite liners more common for gold and silver leach pads Copper run of mine dumps are generally unlined
The second site of the Sarcheshmeh valley leach facility extends over 300 000 irr which may eventually reach heights of nearly 90 m is situated in the west side of the mine This paper discusses the stability analysis of heap leaching structure Hence it is important to be able to assess the bonding properties of the interface between the geomembrane and inclined surface

·A valley fill heap leach is just as it sounds the ore is dumped at the bottom of a valley and is built up filling the valley Valley fill heaps are built in areas that do not have enough level terrain to build an expanding permanent heap
·Leach pads can be divided into four categories conventional or flat pads see Fig 1 dump leach pads Valley Fills fee Fig 2 and on/off leach pads are relatively flat either graded smooth or terrain contouring on gentle alluvial fans such as in the Chilean Atacama desert Nevada and Arizona and the ore is stacked in relatively thin lifts
·thicker up to 50m Valley fill systems are just that leach pads designed in natural valleys using either a buttress dam at the bottom of the valley or a leveling fill within the valley The facility shown in Photo 1 includes a 100 m high buttress dam and will ultimately crest out with 300 m vertical from the toe of the dam to
