As mining moves deeper into the earth and towards more remote locations and the consumer demand for larger diamonds continue the extraction process is becoming increasingly complex and costlyto the environment Each year over 150 million carats of diamonds are extracted from the Earth through mining
Nickel is recovered through extractive metallurgy it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity In many stainless steel applications 75% pure nickel can be used without further purification depending on the composition of

The injectors will be spaced around 20m apart but this distance depends on the flow rate through the rock each bore is about 150 mm in diameter and around 120m deep producing ~ 18m3 of material many images will come up for Uranium mining which requires far more infrastructure than copper mining and should not be directly compared
