The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.

What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that …

Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth's continental crust. Basalt is formed through the rapid cooling and solidification of magma at Earth's surface, resulting in the formation of lava flows […]
