sized flotation cell based on the designed concentrate tonnages and solids content of the concentrate. Wash-water addition is commonly measured as a ratio with the water in the concentrate. A wash-water ratio of 1.0 means that, theoretically, all the „dirty‟ water in the concentrate containing the entrained ash particles is replaced by

Out of 5.0 g of PG taken for floating in water 4.5 g of FG was recovered. Thus, the process of converting PG to FG has 90% efficiency. The reaming 10% is due to the removed inclusion mineral ...
The results from a 21-day trial have shown the following:The ratio of concentrate mass-recovery between two cells in series on the same level has been successfully balanced, thereby overcoming problems due to differences in hydrostatic heads.It is possible to control the speed of the froth, in mm/s, to within five per cent of its setpoint using ...
This study evaluated the effectiveness of using high pH to depress high-concentration pyrite in copper flotation with the performance compared to the depression of low-concentration pyrite. It was found that pyrite was depressed progressively in the flotation with 5 % pyrite feed grade as the pulp pH increased from 9.0 to 10.5 and then …
Why do flotation issues go unnoticed? Several factors could play a role: Lack of real-time monitoring: Flotation processes often lack comprehensive real-time monitoring systems that can provide immediate feedback on performance. Operators may rely on periodic sampling and laboratory analysis, which may not capture transient or …
The gray value of the froth image is the earliest feature used to predict coal flotation performance Tan et al., 2016). In this study, the gray levels histogram distribution of the froth image was ...
Cleaner column flotation succeeded in producing final concentrate grades of 28 to 29 pct Cu and 1.37 oz Au/st with recoveries of 96.1 pct for Cu and 96.3 pct for Au. Effect of Aeration Rate. Flotation columns are generally operated at a maximum aeration rate for any given set of conditions in order to maximize flotation recovery and throughput.
There are many influencing factors for model selection and design of flotation machines. Not only the conditions such as the ore properties, throughput, flotation size, concentration and reagent system shall be considered but also the factors such as the flotation machine type, equipment configuration, investment cost and …

CNNs' implementation in a regression problematic allows for real-time monitoring of mineral concentrate grades, enabling precise assessments of flotation performance.
However, these were focused on monitoring flotation performance through froth structure and typically only estimated the commodity concentrate grade through colour. Recent studies have also utilised deep learning for froth image analysis to estimate the concentrate grade (Fu & Aldrich 2018; 2019).
The optimal performance of the flotation process relies on achieving a suitable balance between the grade and recovery of the concentrate. In many cases, …
