Mining for the Future


Silver ore is mined through both open-pit and underground methods. The open-pit method involves using heavy machinery to mine deposits relatively near the earth’s surface. In underground mining, deep shafts are dug into the ground to extract ore. Once ores are extracted, they are crushed, ground, and separated through a process called “flotation” to achieve mineral concentrations that are 30-40 times higher than naturally occurs. Refiners then further concentrate this extraction through the process of electrolysis or amalgamation.1


The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold.  Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an orebody are deemed profitable (economic) to mine. In times of higher prices, mining low-grade ore will become profitable as the higher price offsets the increased cost of extracting and milling greater volumes.


Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.
