In this paper, a real-world gold-antimony flotation plant in Hunan province of China is discussed. The simplified production flowsheet is shown in Fig. 1.It consists of two main objectives: (1) separate the gold from the raw ore in weak-alkaline environment, while the antimony particles are ensured to be non-floatable; (2) separate antimony under a …

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony …

As illustrated in Fig. 4, at increasing pH of the solution from 3 to 5, the efficiency of HA removal by the AEC-PS process was improved from 87.4 ± 4.5% to 94.3 ± 4.7%, which may be due to the ...

The key point to achieve automatic control and optimal operation in flotation process is to recognize the flotation conditions correctly. By the fact that it's difficult to detect and identify fault conditions in antimony flotation process, a fault condition recognition method based on multi-scale texture features extraction and k-means …

Introduction: The flotation machine is important for realizing the flotation process. It can process metal or non-metal minerals, such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration.

Antimony gold deposits are difficult to recover in flotation separation, on one hand, it owing to the wrapping gold in antimony, on the other hand, it on account of the consumption of cyanide and ...

use of a depressant. Starting with an containing antimony (5.89%), lead (0.34%) and arsenic (0.25%) a concentrate containing antimony 30.68%, lead 1.52% and arsenic 0.85% was obtained without an depressant in a Devnver flotation cell. The addition of a depressant resulted in a concentrate with

Froth flotation is the most critical process for separating stibnite from raw ore. Concentrate grade is a vital production indicator in the antimony flotation process. It is a direct reflection of the product quality of the flotation process and an essential basis for the dynamic adjustment of its operating parameters.

In this research study a convolutional neural network (CNN) is developed to classify the froth images collected from an industrial coal flotation column operated under various process conditions (air flow rate, frother dosage, slurry solids%, froth depth and collector dosage). In the first step, the froth images captured at different air flow ...

A Denver flotation cell was used in this work. Two dosages (0.5ml and 1ml) of frothers were used. The mountain ore mineralogy analysis showed that the ore contained 0.341% copper feed grade. With 0.5ml of Senfroth XP 200, 1.278% of copper was recovered and 0.055% of copper reported to the tailings.
