For conducting a mining project's break even analysis, you first need to know about the operational expenses (OPEX). When the OPEX is known, you can calculate the mineral's cut off grade, which is the break even grade, below which it is not economically viable to mine the ore. To find out how I come up with the cost price per tonne (OPEX ...

Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth . manufacturing cost of aluminium for sale - manufacturing cost.
Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. ... which are generally located close to bauxite mines. Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade ...
Open-cut mining can be more effective than underground methods, generally recovering 90% of a mineral deposit, and accounts for about 65% of raw coal production in NSW. Open-cut mining is also used for some gold and copper production in NSW.

Globally, bauxite mining disturbs a relatively small area of land compared to other types of open cast mining. Around one square metre of land is newly opened up each year to produce one tonne of aluminium, with the same area annually rehabilitated.
The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life." ... any commercial mining operation is the exploitation of the mineral deposit at the lowest possible cost with a view of maximizing profits ...
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.
1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200-400 meters depth in bulk tonnage.. The mining costs are estimated in a mining company's feasibility study which, when available, can be found on the company's website (often hidden between the news releases).

Northparkes Mine Open Cut is a Copper and Gold – mine located 27 km north-west of the town of Parkes in Central New South Wales. NPM is a joint venture between Rio Tinto (80%) and the Sumitomo group (20%). Northparkes Mine operates both underground (Block Caving) and open cut mines on their mining …
IFRS Developments for Mining & Metals: Accounting for waste removal costs – A summary of IFRIC Interpretation 20 3 How should the stripping activity asset be initially measured? The stripping activity asset must initially be measured at cost. This is the accumulation of costs directly incurred to complete
Tailings ponds can also be a source of acid drainage, leading to the need for permanent monitoring and treatment of water passing through the tailings dam; the cost of mine cleanup has typically been 10 times that of mining industry estimates when acid drainage was involved.
In 1927 a major fire soared through the mine workings and the company went into liquidation … but in 1933, after some years of study and a much stronger copper market, the mine was re-opened as a large scale open cut mine and stayed in production until 1982 when the famous mine was finally depleted.
Open Cut Mining There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method.
Underground Mining is a method of Mining, where the mineral is extracted without removing the top soil and rocks. In this way we do not disturb the surface feature …

The cost advantage of open pit mining to investors is a matter of scale. According to the Delta Mine Training Center an open pit mine is cheaper, safer, and mechanically easier to operate.
Technologies in Exploration, Mining, and Processing INTRODUCTION The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use.
Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow
Open-pit mining utilizes blasting and mineral removing, digger deeper into the earth causing a crater-like result. ... Is deep drilling worth the cost? While underground mining requires an array of resources, equipment and financial backing, the method is best suited if the environment and coal potential harmonize. Longwall mining accounts for ...
Several benches may be in operation simultaneously in different parts of, and at different elevations in the open pit mine. Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

There are currently five bauxite mines in Australia providing feedstock for the seven alumina refineries, which in turn supply alumina to the six Australian aluminium smelters and the export market. Australia is the largest producer of bauxite in the world, with 74.9 million tonnes produced in 2011.
