FLSmidth DorrOliver Eimco Flotation Technology
Combining flotation cells with markedly different processing actions into a single process bank increases recovery rates. The Wemco design with the agitator near the top of the cells has excelled on coarse particle recovery and the DorrOliver cells excelled on fines and concentrate grade. On large cells, we have developed a "Universal Tank" that can accommodate either the Wemco induced ...

Cominco Lead, Zinc and Silver Mine
The mill grinding sequence consists of Fuller SAG and ball mills, which reduce the ore to 80% –65µm for primary flotation. Tower mills regrind to Zn 80% –22µm and Pb 80% –19µm. Treated water is used in the grinding circuit to minimize metal ions that inhibit flotation performance. Flotation is carried out in Maxwell cells, retrofitted with Outokumpu mechanisms, and in CESL column ...
CHAPTER 3 COMPARISON OF DIFFERENT PYRRHOTITE .
780 ml tap water in a steel ball mill for 20 minutes. b. Magnetic pyrrhotite removing : The mill product was placed in a 4 L flotation cell (or any other cell), and tap water was added to fill the volume. While the slurry was being agitated, a hand magnet was then immerged into the slurry to collect magnetic pyrrhotite on the magnet. This process was repeated until the magnet did not remain ...

Electrochemical aspects of grinding mediamineral ...
wet grinding in ball mills is an essential step before any flotation process. In ore grinding, grinding balls come in contact with freshly generated mineral surfaces in the presence of oxygen and an aqueous electrolyte. Galvanic interactions involving grinding media and mineral surfaces could thus take place in a mill with the active steel ball material undergoing corrosion while the relative ...

· This rotating drum contains steel balls that more crush the ore to a fine powder. If the ore / lime slurry emerges on the mill, it ... as you move the overflow will be discharged to flotation cells. Air is injected into the flotation cells, and foaming agents are added, developing a froth. Copper ore particles, because of the relatively lightweight, become a part of this froth, while heavier ...
Ball Mill
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement ...
IsaMill
While most grinding in the mineral industry is achieved using devices containing a steel grinding medium, the IsaMill uses inert grinding media such as silica sand, waste smelter slag or ceramic balls. The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can ...

Introduction to Mineral Processing or Beneficiation
· Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed cm. The grinding is carried out by balls being carried up the side of the mill such that they release and fall to the point where they ...

· Mild steel and ceramic laboratory ball mills were used to grind 600 g sulfide ore charges. The mild steel ball mill generated approximately g of iron fines (% of the ore charge mass) when grinding to a product size of 80% passing 200 mesh (75 /μn). When a low dosage of a weak xanthate collector was used in flotation, the impact of the iron fines on sulfide flotation was marked. Higher ...
