One of the current challenges for iron ore producers is the ability to respond to changes in ROM stockpile specifications in a quick and cost-efficient manner. The decision-making process to respond to such changes is normally associated with grade-control and short-term mine planning activities, from where new operating instructions to the mine are …
Inhalation of excessive concentrations of iron oxide may enhance the risk of lung cancer development in workers exposed to pulmonary ca rcinogens. According to a study by Boyd et al. (1970) who investigated the mortality of 5811 Cumberland iron-ore miners who died between 1948 and 1967, the miners who work underground suffer a lung cancer mortality

The ROM ore is crushed using four in-pit gyratory crushers before being transported to the concentration plant.
A stockpile treatment for dust control and erosion prevention was conducted at ASSMANG Khumani Iron Ore Mine, whereby two adjacent stockpiles were documented, one was treated with a surface application of EBS Soil Stabilizer, while the other was left untreated.After three months 169 tonnes of material was lost from the untreated …

Purpose In the mining industry, a run-of-mine (ROM) stockpile is a temporary storage unit, but it is also widely accepted as an effective method to reduce the short-term variations of ore grade.
This study aims to build a three-dimensional (3D) model for ROM stockpiles continuously based on fine-grained grade information through integrating data from a number of ore grade tracking sources.,Following a literature review, a framework for a …
Robe Mesa Iron Ore Project Location. The Robe Mesa Iron Ore Project is located in the West Pilbara, Western Australia. The site is within the Shire of Ashburton, around 175km by road from the town of Onslow . The project forms a part of the Robe Valley channel iron deposits (CID) and is situated immediately north of Rio Tinto's Mesa F iron ...
Stockpile blending is always considered to be an effective method of controlling the quality and maintaining the grade consistency of delivered bulk material, such as iron ore. However, major challenges remain to predict the quality of a stockpile during blending (stacking and reclaiming) operations, because the chemical composition …
was tested on a scaled down stockpile model and results demonstrate good, precise and fast performances. Keywords: Stockpile modelling, Laser scanning, Voxelziation, Quality control. 1. Introduction Iron ore quality is evaluated by two measures during exports: the quality composition of the ore and the short-term grading consistency.
The frequent best practice for managing large low-grade run-of-mine (ROM) stockpiles is to average the entire stockpile to only one grade. Modern ore control and mineral processing procedures need better precision. Low-precision models hinder the ability to create a digital mine-to-mill model and optimize the holistic mining process. …
Experiments conducted with a 75-mm-diam hydrocyclone have shown it is possible to obtain an iron ore concentrate containing 60% Fe, 2.65% SiO2 and 4.0% Al2O3 from Barsua iron-ore washing-plant …

With optimization, the optimal proportion of imported iron ore fines is 15%, fuel rate is 5.4%-5.5% correspondingly. The proposed proportions of iron ore fines and fuel rate were approved by practice.
However,tracing ore grade at ROM stockpiles accurately using most current fleet management systems is challenging, due to insufficient information available in real time.

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 …

The iron ore stockpile (formerly known as the "ore cutter") is a construct used to store iron blocks. It's required in order to later process these blocks at the stone cutter or stone cutter II into iron ore. It does not have any particular function of its own outside of this. Only 7 blocks of iron can be stored in a stockpile at a time. The one that can be built in the …
