Biotite granite was sourced from the Este Porphyry at Chiquecamata, Chile. The mineralogy is dominated by plagioclase and orthoclase feldspar, quartz and biotite, with moderately coarse (2–8 mm) equigranular crystal texture (Fig. 1 a). Biotite is locally altered to chlorite along fractures and at crystal edges, and small chlorite crystals …

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 […]

Basalt makes up most of Earth's sea floor, as well as Iceland and the Hawaiian Islands. Despite being an extrusive igneous rock, basalt has a lower mining time than granite and diorite, which are intrusive. Basalt is the only rock-like block to have both a polished and smooth variant.

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.
