Newcrest Mining is working with Microsoft and Insight Enterprises to deploy Microsoft cloud, AI and IoT technologies at Cadia Valley in NSW, to monitor and manage crushed ore levels 29 October 2019 Managing the levels of the crushed ore bins was problematic at Cadia in the past, according to Newcrest digital and data science architect …
An early trial of using soft sensors in the Cadia mine involved assessing the capacity of crushed ore bins that sit underground. ... able to have a better understanding of the levels in those bins ...
These ore bins held and fed rock to a stamp battery that crushed ore into a sandy-watery pulp and pushed it onto an amalgamation table where the precious metals were extracted. Though the mine operated some 40 years, ownership and details about the mine's riches are sketchy. ... Two ore bins, a dirt-covered shelter, and an abandoned …
A 21-foot diameter cylinder with a 14-foot wide by 17-foot 8-inch long "tail" was undercut by the conveyor drift below. The ore bins, each 28 feet in diameter and 90 feet deep, were cut in much the same manner as the crusher chamber. Undercutting the bins reduced the depth of hole required to 73 feet. To achieve a smoothwall effect, 2-¼ ...
At the mine site, the run-of-mine (ROM) ore, as well as crushed ore, needs to be stored, reclaimed, and conveyed reliably, whereas at the processing plant, the concentrate needs to be fed reliably to furnaces, calciners, roasters, or smelters. ... Particle size segregation in stockpiles and bins can cause problems particularly when handling ...

Crushed ore bins under control at Cadia. NEWCREST Mining has automated the underground crushed ore bin monitoring process at the Cadia Valley …
The challenge facing Newcrest at Cadia was managing the levels in the underground crushed ore bins. If the bins overfill, they have to be manually emptied introducing lengthy and expensive production delays. Conversely, if the level drops too low it is unable to effectively feed the collection conveyor. Newcrest had spotters, physically ...
collect the caved ore from drawpoints and tip the ore into run-of-mine (ROM) ore bins feeding jaw-gyratory crushers. The crushed ore is subsequently passed to surge bins that provide material onto a series of collection conveyors. The main trunk belt fed by the collection conveyors transports the ore to the surface at a conveyance rate of 4600 ...
The crushed ore is conveyed to a traversing rock box and thence to one of two crushed ore bins adjacent to the main hoisting shaft. A loading station conveyor is interlocked with the winder to provide automatic ore hoisting.All phases of ore handling have been mechanized as completely as possible. Results to date indicate this policy has been ...
Newcrest had people watching the bins to ensure they didn't overfill – but it was an unpleasant job. Now, using Microsoft Azure, Newcrest takes data from its crushed ore bin soft sensor, then uses intelligent edge AI and data science techniques leveraging a machine learning algorithm that predicts the level of crushed ore in the bin.

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 best ore contained 60-65% copper. (Left) These massive timbers supported the 400-ton crushed ore bins. Next the ore was passed through a trommel. Oversize material went to conveyors where the highest grade ore pieces were hand-picked for direct shipping to the smelter in Tacoma, Washington.
crushed ore to be distributed to conveyors 4A or 4B that in turn allows the crushed ore to be distributed to the Fine Ore Bins ahead of the North and South Milling Trains. The Fine Ore Bin has a live capacity of approximately 13 hours and feeds eleven groups of 12 vibrating feeders, one group for each of eleven Milling Trains.
The crushed ore is then hoisted to the surface and stored in crude ore bins, with a capacity of 60,000 tonnes. A conveyor moves ore from these bins to another crusher, where it is reduced to about 10 mm, and passed to fine ore bins. The ore then goes to a rod-and ball crusher for fine grinding, and is pumped to a floatation process, which ...
When material is crushed and removed from the mortar, the stamps are able to fall lower in the mortar and the rocker arm will again be stuck by the tappet causing the table to rotate and feed more ore into the mortar. ...
HAWK Measurement provides a variety of products to measure segments within mining such as crushed ore and coal surge bins. Speak with a representative today!
All the ore delivered to the Mill's ore bins were first crushed to a more uniform size (2 inch maximum), then transferred to elevators for additional processing in the upper levels of the Mill. Name: Preparing Argo equipment for display. Date: Circa 1980 Phase: Maxwell years
The ore is crushed underground to minus 6 in. and hoisted to 140-ton surface bins. From there it is fed to a 7-ft. cone crusher after passing over a double-deck screen that removes 1¼-in. undersize from the crusher feed. The product of this crusher plus the product of all other crushing units in the plant is then conveyed to …

Crushed material is conveyed to a screen and the oversize is returned to the secondary cone crusher. The screened fraction drops to a reversible conveyor, thence to fine ore bins. Adjustable stroke belt ore feeders regulate the feed to two 5′ x 10′ Steel Head, Ball Mills, in a closed circuit with Cross-flow Classifiers.
Although every plant uses a different form of ore storage, there are 3 basic types of storage used in the oil sands: (1) stockpiles, (2) concrete silos and (3) surge bins. TYPE 1. STOCKPILE. The simplest form of ore storage comes in the form of a stockpile, a technology borrowed largely from the coal mining industry.
