The iron ore produced is transported through trains to Saldhana which is approximately 861 km away from the mine. The in-situ ore types are laminated ore, conglomerate ore and detrital ore. The major ore bearing mineral is Hematite (Fe 2 O 3) which constitutes 93% of the orebody mass. The material mined is separated into ON grade ore, OFF grade ...

Stockpile measurement can be performed using two methods, which can also be used in combination. Stockpiles managed with tripper cars, A-frame reclaimers, or similar handling equipment are outfitted with a position sensor and a 2D radar …
Stockpile measurement works by using total stations or Laser Scanner to measure the size of stockpiles and then combining this with data taken from density surveys. In order to calculate the overall mass of your stockpile, we require two key pieces …
The most expedient method of measuring the degree of particle coherency within an iron ore pellet is the crushing test. A specific test carried out as a measurement of value, such as the crushing strength of fired pellets, is only as good as the degree of reproducibility of the test. Results of Laboratory Pelletizing Tests
Stockpile volume in a few Minutes. Simply walk around a free-standing stockpile or pit and scan its surface with your iPhone or iPad. You can define the toe-point polygon and reference plane by measuring it with the crosshairs on the video screen or by using one or more ground control markers (GCPs) which are detected automatically by StockAce.

Managers of bulk solids carefully monitor their stockpile height measurements for both overfill prevention and inventory management. These directors of heaped goods — such as grain, gravel, ore — are often looking for stockpile measurement with …
The stockpile mass estimation method proposed by TUNRA Bulk Solids accounts for both the stockpiled material's compressibility as well as the consolidation states throughout the stockpile. As shown in Figure 6, a surface scan and a compressibility function similar to that shown in Figure 3 are used to compute the stockpile mass.
From the chart above the volume of the stockpile can be approximated to 100 m 3. Example - Stockpile Volume in Imperial Units. The floor diameter of a stockpile can be measured to approximately 10 ft and the height of the stockpile can be measured to approximately 4 ft. From the chart above the volume of the stockpile can be approximated to 100 ...
Both lines are fed from a coarse ore stockpile (COS) with a live capacity of approximately 500,000 t of primary crushed ore. In this thesis, the results are presented of the analysis conducted on ...
measurement. Further improvement in quality control therefore depends on controlling the variability in composition between successive stockpiles. The port yard comprises an array of stockpile sites. If ore is stacked on arrival to a single stockpile, which is …
Stacking and reclaiming ore through a stockpile is a low-pass filter, filtering out short-period variations in composition. The simulation reports Fourier analyses to explore the filtering.

Clear stockpile boundaries : It's always good to have a clear visible boundary of the stockpile. If the stockpile is against some other entities, and you cannot select boundary points on a flat ground, it's better to use lowest elevation base plane volume.
This paper provides a review of base and precious metal run-of-mine (ROM) pre-crusher stockpiles in the mining industry, and demonstrates how to build a spatial model of a large long-term ...

In the minerals and mining industry, effective stockpile level monitoring is essential to maintaining operational efficiency and optimizing resource utilization. For this application, we must use a non-intrusive technology. Both Radar and Acoustic stockpile measurement equipment will work within reason. For high-speed fill rates, the Acoustic transmitter will be the best option, as they can ...
stockpile approximately 500 Mt of copper ore, for up to 20 years. Much of the copper is present as the copper sulfide chalcopyrite. Construction of the stockpile commenced in late 2000 and as of early 2007 the pile contained regions more than 100 m high. Oxidation of chalcopyrite in stockpiled ore results in reduced copper recovery during ...
Accurate & Fast Stockpile Volume Measurements. Regardless of what's in the stockpile, whether it is coal, asphalt, sand or anything else, we have the ability to measure the contents precisely.
Comminution circuits generally have a coarse ore stockpile after the primary crusher to decouple the relatively uneven mined ore supply from the downstream comminution and concentrator circuits...
and accurate measurement of mineral commodities is obtained. Our stockpile measurement system can accurately measure stockpiles for commodities including: • Coal • Fertilizers • Iron ores Stockpile measurement is a technique to measure the volume and weight of commodity stockpiles. It is a scientific/ instrumental method, using Total Station
Design options for pre-crusher stockpiling should consider the four competing roles of storage, buffering, blending and grade control, to produce predictable and uniform crusher feed grades.

The crushability factor is the ratio of the crusher's ability to crush pending ore and the crusher's crushing medium-hard ore under the same conditions. Limestone is usually used as the standard medium-hard ore, and its crushability factor is one. (2) Work index method. A double pendulum impact testing machine is used to measure the impact ...
We believe measuring stockpiles should be easy. With this in mind, we developed stockpile measurement solutions tailored for building material companies. There are various stockpile measurement methods. Stockpile Reports has ranked them from most affordable and efficient to the least efficient and expensive. #1 Measure Stockpiles with an iPhone
3d stockpile measurement system The 3D laser Scanner gets mounted on the top of the stacker/ reclaimer machine and scans the entire stockpile to provide a real time 3D Profile and Volume of the Stockyard as the machine is in operation, thus allowing for accurate inventory management with real time Volume, Mass and 3D Profile of the Stockpile.
Four key objectives of storing, safety, grading and measurement impact stockpile management. Product handling. Mining equipment brings material to the surface, crushes and screens the loads, then hauls and stockpiles into multiple stacks. A simple stockpile forms when dump trucks or bulldozers deposit bulk quantities of ore or coal into a pile.

A typical coarse ore stockpile (Fig. 1) is fed from either a fixed or moving conveyor with primary crushed (minus ∼ 250 mm) rock to build up a pile above one or more fixed discharge feeders or draw points.These feeders discharge onto one or more belt conveyors that in turn each feed an autogenous grinding (AG) or semi autogenous grinding (SAG) mill.
