13Apr. Potential and limitations for sensorbased particle sorting of gold ores experiences on sensorbased particle sorting piloted for SAG pebbles
In 2006, Wotruba encouraged the mining industry to consider sensor ‐ based ore sorting in the earliest planning and flow ‐
Several factors contribute to an often bleak outlook for mining and mineral processing projects in the current market: rising energy costs, falling ore body head
The modeling of sorting behavior in this test enables design engineers to focus their improvement efforts and is designed to complement the wide range of tests
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will
The impacts of ore sorting on the economics and the process flow sheet of an existing semiautogenous milling circuit of a US copper mine are discussed. View Show abstract
Ore Dilution & Recovery in Mining. Apr 05, Hand sorting is often employed to remove coarse gangue material with resultant raising of the grade of the ore
The energy costs required to refine metal values contained in ore to concentrates constitute the majority of the cost to produce metals. On average across the mining industry, 44% of the total electricity consumption is dedicated to crushing and milling activities ().Size reduction operations, nearly 150 × 10 9 kW h, are the largest single
The operation is a large, conventional truck and shovel openpit mine, mining at an average rate of around 60 Mtpa (ore and waste). The processing plant can now treat up to 20 Mtpa of ore, with a copper recovery
13Apr. Potential and limitations for sensorbased particle sorting of gold ores experiences on sensorbased particle sorting piloted for SAG pebbles ABSTRACT A comprehensive energy study was carried out for the Red Chris mill, which processes coppergold ore at a rate of 30,000 tonnes per day (t/d) and is located in
Bulk ore sensing and sorting enables the preconcentration of the concentrator feed while simultaneously improving its consistency. It sets a foundation for better performance in all subsequent operations delivering dividends by: Increasing resource utilization. Adding throughput with no plant expansion.
The STEINERT XSS® T EVO 5.0 with ‘dual energy’ xray transmission (XRT) is ideally suited for ore sorting because the xray radiation can penetrate stones with particle sizes up to 100 mm. Metals can thus be detected, even when they are not on the surface. By altering the configuration of the machine, you can select the desired minimum
A large portion of the energy consumed in copper concentrators is used to reduce the particle size of the feed by crushing and grinding. The cost of metal production could be reduced if lowgrade particles of cm size were removed prior to further processing. Two copper sulfide ore samples (3 × 1 cm) from Arizona were analyzed by micro Xray
Effective sorting can be done down to 1 mm but not necessarily with a electromagnetic sensor based ore sorter which may be more happy processing particles upwards of 3 mm. Economical sorting is
Three particles sizes were tested with the sorting equipment in the laboratory: −25 + 9.5 mm, −50 + 25 mm, and −70 + 50 mm. We use indices of recovery, in terms of Calcium Carbonate Equivalent and mass balance, but also performance indices as accuracy, sensitivity, and specificity for interpretation. Recovery values were between 35
Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.150.2mm. Copper ore crushing process. 1.
Hand sorting inherently suffers from low efficiency, low capacity and high cost. Although there are applications down to 20 mm, practical lower limit for hand sorting is 4050 mm. Development of
Sensorbased particulate ore sorting is a preconcentration technique that sorts particles based on measurable physical properties, resulting in reduced energy consumption by removing waste prior to grinding. This study presents an integrated methodology to determine the potential for ore sorting based on intrinsic particle

Doré Copper Mining Corp. aims to be the next copper producer in Québec with a production target of +50 Mlbs of copper equivalent annually by implementing a huband spoke operation model with
Introduction. As part of the evaluation of Bulk Ore Sorting (BOS) at the Phu Kham operation, this paper describes the analysis used to predict optimum cutoff grades for the mine and bulk ore sorter to maximize economic results. The objective was to present a methodology which could be applied to brownfield and greenfield projects by estimating
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and
Ore sorting technology evaluation study adds value for client. A client in Australia engaged us to explore valueadding opportunities and technologies for a greenfield development of a copper mine and concentrator. By taking a holistic approach to the entire project’s economic evaluation, we were able to deliver a significantly better outcome.
TOMRA Sorting Mining has delivered its first underground sensorbased ore sorting solution to K+S Minerals and Agriculture at its rock salt mine in Grasleben, Germany. The major salt producer looked to TOMRA, which it has a longstanding research and development relationship with, to replace an existing sorting system at the mine.
Three particles sizes were tested with the sorting equipment in the laboratory: −25 + 9.5 mm, −50 + 25 mm, and −70 + 50 mm. We use indices of recovery, in terms of Calcium Carbonate Equivalent and mass balance, but also performance indices as accuracy, sensitivity, and specificity for interpretation.
