U.S. Mining Industry Energy Bandwidth Study

This mining industry energy bandwidth analysis was conducted to assist the Industrial Technologies Program’s (ITP) Mining subprogram, an initiative of the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE), to maximize the impact of its R&D in reducing industrial energy consumption. Although the study

Market Underestimates Energy Consumption By The Gold

While the gold mining industry reports energy as only 15-20% of its total production costs, the total amount consumed by the industry is much higher. The market underestimates the amount of energy consumed by the gold mining industry because of the way it is listed in their financial statements. Thus, it takes a great deal more energy to produce gold than the market realizes.

Energy Consumption in Mining Comminution

2.1 Energy Consumption in Open Pit/ Underground Mines There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where

Specific energy Wikipedia

Energy density has tables of specific energies of devices and materials.. Specific energy or massic energy is energy per unit mass.It is also sometimes called gravimetric energy density, or just energy density though energy density more precisely means energy per unit volume.It is used to quantify, for example, stored heat and other thermodynamic properties of substances such as specific

Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The statistical analysis of gold prices in the first part was complicated by the fact that price data is often hard to get, incomplete or sometimes non-existent. However, the same problems are compounded when it comes to actual data on energy consumption by the gold industry. Gold producers are not required to disclose their energy consumption
