Step 1: Rotary drills bore 48 foot holes, 9-7/8 inches in diameter, into the granite host rock. Step 2: Drill cuttings are assayed to verify composition. Step 3: Drill holes are loaded with explosives to blast and fracture the rock. Step 4: Electric shovels load ore into haul trucks

energy and cost comparisons of hpgr-based circuits | e & mj

The U.S. Department of Energy reported that there is a potential to reduce energy consumption in the metals industry by up to 61% from current practice to best estimated practical minimum energy consumption; suggestions included the implementation of best practices and the adoption of energy efficient mining and mineral processing technologies

energy efficient technologies for the mining industry

Jul 01, 2010 · The objective is to reduce energy usage in metal mines by 20 per cent overall. Open pit copper, gold and molybdenum mines are being targeted. Projects underway at UBC were outlined, with particular reference to energy usage, recovery and alternative energy sources; preconcentration; reducing energy usage from comminution in sorting, high pressure grinding rolls and high speed stirred mills; Hydromet; other energy efficient technologies

increased production and energy efficiency for optimized

Apr 24, 2014 · Compañía Minera Antamina is a polymetallic mining complex that produces copper and zinc concentrates as primary products and molybdenum and lead/bismuth/silver concentrates as by-products. Antamina, situated in the central Peruvian Andes some 4,300 meters above sea level, represents one of the main complexes of the Peruvian mining industry

interactive energy resource map - arcgis storymaps

Mining engineers design safe and efficient mines for removing minerals and energy resources. They optimize the mining process for removing resources in the most efficient manner possible, ensuring as much of the resource as possible is extracted. Mining engineers tend to specialize in a particular mineral or metal, such as copper or coal

energy efficiency | department of energy

Energy efficiency is one of the easiest and most cost effective ways to combat climate change, clean the air we breathe, improve the competitiveness of our businesses and reduce energy costs for consumers. The Department of Energy is working with universities, businesses and the National Labs to develop new, energy-efficient technologies while

freeport-mcmoran slashes carbon emissions by 21 percent

Copper mining firms worldwide are committed to reducing their carbon emissions. Freeport-McMoRan, one of the world’s largest copper miners, lowered its carbon emissions by more than 21 percent from 2015 to 2019. This puts the company on track to meet the COP21 framework to limit global warming to below 2°C from pre-industrial levels by 2050

new manufacturing technique for flexible electronics

Jun 17, 2021 · Ultrathin, flexible computer circuits have been an engineering goal for years, but technical hurdles have prevented the degree of miniaturization necessary to achieve high performance. Now, researchers at Stanford University have invented a manufacturing technique that yields flexible, atomically thin transistors less than 100 nanometers in length—several times smaller than previously
