Iron Trail with Erzberg and the old town of Steyr
The Erzberg represents the most prominent ore mining example in Central Europe. The formerly preferred and now exclusive open pit mining process with its imposing worked terraces has resulted in a stepped shape of the entire mountainside. The former ore smelting industry in Eissenerz featured 19 ironworks dating back to the 16th century.

This work evaluates and characterizes the impact of the support size and mining dilution of a block model in the operation and selection of equipment at an open pit mine. An exploratory analysis and geostatistical modelling of the grades assayed on a set of drill hole samples is performed, which allows constructing a grade model on a dense grid by means of a conditional .
Pit Optimization – How I View It
· Pit Optimization – How I View It. One of the first steps in open pit mine design is the pit optimization analysis. Pit optimization is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters include the metal prices, process recoveries, and operating costs.

Open pit mining by its very nature normally involves the haulage of moderate to large amounts of waste and ore to out of the pit for relatively long distances at steep grades. These requirements affect the layout of the pit, selection of equipment, and production rate.
Green Mining
Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).
Selection of OpenPit Dump Trucks during Quarry ...
· The mining enterprises could incur significantly greater quarry reconstruction costs to create the necessary transport communiion with security conditions if they are guided by the initial cost of openpit dump trucks and costs on their consequent service by selecting openpit dump trucks in the same class of loading capacity.

Sintering: A Step Between Mining Iron Ore and Steelmaking
· Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel.
