As a rule of thumb, open pit mining can process ore for $10 per tonne and, where the ore grade is more than double that at $20 per tonne, results would be economic. Consider that 1% of a metric...
The grade control process is described below: DRILLING: Drill burden and spacing are based on the rock types present at Skorpion , e.g. 4 m x 4 m in ore and 6 m x 6 m in waste material (Figure 2). SAMPLING: Samples and drill chips are collected over intervals of 2.5m, 5m or 10m.
At one point in an operation, mining becomes unprofitable because the grade of the metal is too low – the value of the metal in the ore is less than what it costs to mine it. Grade control stops businesses from running at a loss. Milling. The milling process is designed to be as efficient as possible by being performed at a specific grade.
Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust. Before the heavy investments required to set up a mining operation is done, the mining organization is to ensure that the deposit is economically viable and it has quantities of ore that will ensure ore production over a sufficiently long period of time.

Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust.
Today will take a closer look at grade control and how it can improve the mining industry. What is Grade Control? Grade control is an essential part of the mining process because the metal being extracted from the ground is never constant.he first grade control machines to have guidance systems were introduced in the late 1990s.
monitors ore tonnes and grades on stockpiles to enable optimal blending for the required plant process performance. The grade control process is described below: DRILLING: Drill burden and spacing are based on the rock types present at Skorpion , e.g. 4 m x 4 m in ore and 6 m x 6 m in waste material (Figure 2).
Ore grade reconciliation can be put into three broad categories: temporal, spatial and physical [ 8]. In Fig. 1, the mining value chain pyramid has reconciliation as the reality check between the various layers. The figure shows how these classifications of reconciliation relate to the various activities of the entire mining value chain.

Mining - Mining - Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and
The process of mining of iron ore from discovery of an iron ore deposit body through extraction of iron ores and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the iron ore deposit, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

The mining process is vital to the American economy. Learn how these 6 steps turn ore into the resources we need.
Ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others. Mining geologists perform ore grade control in underground mining operations to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. By performing ore grade control, mining operators are also reducing risk ...
Grade control is a process of maximising value and reducing risk. It requires the delivery of tonnes at an optimum grade to the mill, via the accurate definition of ore and waste. It essentially...
Abstract. In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.

Mining grade and sampling theory—the logical way to evaluate ore reserves proportion. An example is 2.5 cm3 m-3 native gold meaning that 2.5 cm 3of native gold are likely to be found in 1 m of country rock. For the conversion from metal-mass grade to

In an effort to minimize the cost of mining and maximize the recovery of ore, careful Grade Control is an integral and essential part of both open pit and underground mining operations. The grade control module provides you with tools to automate and simplify the more mundane aspects of production control tasks. This article provides solutions ...
As mining technology developed, steam powered beam whims were constructed to do this, later to be superseded by horizontal steam winders. Mining was a family occupation, with women and children working on the surface dressing the ore.
