run of mine rock fragmentation
Run-of-mine fragmentation is an important aspect of mine productivity optimisation, as it affects all mine-to-mill process In this study, a 3D rock fragmentation measurement (3DFM) system is proposed that can surmount the limitations of conventional 2D photo-based rock fragmentation measurement methods
Rock Fragmentation by Blasting - Orica
The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can achieve significant improvements in waste productivity, mill throughput, fragmentation profile and wall stability.
Prediction of Rock Fragmentation Using a Gamma-based Blast ...
A blast fragmentation model is developed based on the gamma function to describe the run-of-mine fragmentation distribution. The model presented is aimed to benefit from simplicity in application and also to be efficient in description of the fine to coarse part of the blast rock fragments.
A New Technique for Predicting Rock Fragmentation in ...
Preliminary predictions of fragmentation in two types of rock blasting, a large hole open pit mining blast and a tunnel round, indicate that the new technique for fragmentation prediction has the potential for predicting fragment size distributions within the rock removed by the Blast.
Development of 3D rock fragmentation measurement system ...
Run-of-mine fragmentation is an important aspect of mine productivity optimisation, as it affects all mine-to-mill processes. In this study, a 3D rock fragmentation measurement (3DFM) system is proposed that can surmount the limitations of conventional 2D photo-based rock fragmentation measurement methods.
Blast optimization - liming
Optimizing blast fragmentation to improve comminution efficiency. The Run-of-Mine (ROM) size distribution has a large impact on the performance of downstream crushing and grinding processes. The in-situ ore properties, drill blast pattern, and properties of the explosive govern the size distribution of rocks produced from a blast and the energy efficiency of the blast.
Prediction of Rock Fragmentation in Open Pit Mines
Three types of rock such as oxide, top magnetite and bottom magnetite are extracted in Gol-e-Gohar Iron Ore Mine. During the rock dimensions study, it is attempted to select 50 patterns until the fragmentation of all three rock types are being evaluated. Also waste and soil fragmented distribution are measured during shovel loading.

Influence of Blasting Parameters and Density of Rocks on ...
The run-of-mine (ROM) fragmentation is considered acceptable when it is fine and loose enough to ensure high efficiency in materials handling. Tschudi is a low-cost open-pit mine extracting oxidized copper ore to be treated through heap-leach, solvent extraction and electro-winning.
Measurement of Size Distribution of Blasted Rock Using ...
fragmentation plays an important role in order to control and minimize the loading, hauling, and crushing costs. The size distribution analysis of the rock fragmentation by sieving is a direct and accurate method but it is very time consuming and costly. Fragmentation analysis by digital image processing is a low cost and quick method.

Rock Fragmentation by Blasting – a review The rock fragmentation process in mining currently being practiced in India needs re-examination to improve the productivity of the mine.
Mine-to-process integration and optimization
Likewise, grind size strongly affects subsequent separation stages. Mine-to-process integration optimizes each stage while considering the impact on the overall operation. Ore characterization. Blast fragmentation and comminution are primarily influenced by rock …
A new framework for evaluation of rock fragmentation in ...
Apr 01, 2019 · A model incorporating Rock Engineering Systems (RES) method was proposed by Faramarzi et al. (2013) to predict rock fragmentation in Sungun copper mine in Iran incorporating 16 effective parameters. Their model was compared by regression analysis and Kuz-Ram model. They concluded that the RES approach is more reliable than other two methods.
