Whether mines recover precious metals such as gold, silver and platinum or base metals like zinc, copper and lead, they all face similar challenges. As the world's most valuable ores have already been mined, they are now left to process ores with lower metal content, making it essential to extract secondary metals as byproducts to maximize revenue.

Feb 24, 2022Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground over time. To remove the ore, boring machinery drills holes into the rock, and even explosives are used to break the rock apart. Globally, approximately 80% of copper production is taken from various sulfide sources.

During copper (Cu) production, the concomitant arsenic (As) is generally dispersed into various As-bearing byproducts which need to be disposed separately. This work presents an integrated disposition method for the hazardous As by returning the As-bearing byproducts to the copper flash smelting process and solidifying As into smelting slag.

Cornish Lithium lead geologist Lucy Crane walks through a forest towards an old processing plant at United Downs. An area once dominated by copper and tin mines, the location - in Gwenapp, Cornwall - is the site of exploratory drilling for lithium, and also the Deep Geothermal Power Project, which aims to use heat from the earth as a domestic power source.

The mining process is done in three stages. First, holes are drilled and loaded with explosives that are set off, and the ore breaks apart. Second, the loosened ore is now mucked or scooped and put into special underground haul trucks. Each truck delivers roughly 100,000 pounds of ore to the surface.

Encouraged by this colorful evidence, in 1820, a group of local farmers got together and formed The Farmers Company and began purchasing mineral rights in the area in order to produce copperas. By 1833, the aforementioned Richardson farm was surveyed by an Issac Tyson, described as "probably the leading industrial chemist of the day".

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.

In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent nickel.

Copper mining accounts for about 2/3rds of annual copper consumption with recycling picking up the balance. And though there were lulls in exploration and discovery during the bear-market-low prices of the 1980s and the several years on both sides of the turn of the century, mined production has continued to rise over time.
