Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, and specifically, to a flotation machine with a carbon removal structure. Background Technique

[0002] A flotation machine, short for a floating ore dressing machine, refers to the mechanical equipment for completing the flotation process. In the flotation machine, the pulp after adding reagents is agitated and aerated, so that some of the ore particles selectively adhere to the bubbles; they float to the surface of the pulp and are scraped out to form a foam product, and the rest remains in the pulp to achieve the purpose of separating minerals. When mining and processing ores, some gold-bearing ores belong to refractory ores of the type with high arsenic, carbon, and high-sulfur fine-grained gold inclusions. Based on the analysis of the ore dressing test, it is found that the arsenic, carbon, and sulfur content in the ore is one of the key factors affecting the ore dressing technical indexes. According to the investigation of the previous production process, it is known that due to the good floatability of carbon and sulfur, etc., a reverse flotation phenomenon occurs in the cleaning area, that is, the grade of the middlings is higher than the grade of the foam. Therefore, the carbon and part of the gold-bearing sulfide ore in the ore material are first floated out by the flotation machine.

[0003] However, the existing flotation machines are not convenient for agitating the ore material at the bottom, and it is not convenient for the carbon and part of the gold-bearing sulfide ore in the ore material to float out; moreover, it is not convenient to separate the carbon, part of the gold-bearing sulfide ore and the foam in the floating foam, and it is not convenient to process the subsequent carbon and gold-bearing sulfide ore. For this reason, we propose a flotation machine with a carbon removal structure. Content of the Utility Model
