Savona Equipment is a flotation cell supplier worldwide. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry.
A schematic of a flotation column is shown in Figure 1. Industrial flotation columns are 6-14 m in height from the bottom discharge . to the top lip, and range in diameter from 0.5 to 5 m. Recent large scale applications have typically been 4 to 4.5 m diameter and approximately 12 m tall. There are many installations of columns that are rectangular. The fabrication cost
Column flotation offers many advantages including Improved metallurgical performance Improved control Less energy consumption Reduced plant footprint Reduced capital requirement Contact Cell Flotation. The flotation contact cell is a slurry aeration device with no moving parts. The contact cell consists of two main components
11.3.3 Flotation equipment. Column cells have been developed over the past 30 years as an alternative to mechanically agitated flotation cells. The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs.
Column Flotation Cells are an integral part of that circuit. Expanding on the historic supply of Pyramid flotation columns, our modernised column cell offering includes design elements focused on improved metallurgical performance and enhanced mechanical design. This approach considers the main elements of column flotation froth washing, froth recovery, residence time,

Efficient flotation for all applications and wide particle size range. There are many factors that can affect your flotation process. The two aspects that have the strongest impact on a flotation circuits efficiency and performance are metallurgical recovery and flotation cell availability.
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5 Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
Columns perform the cleaning stage in a large sulfide copper concentrator, following rougher flotation in tank cells. Scavenger of the cleaner tailings is performed in tank cells at this plant.
range of cell sizes on the market, from 5 to 630 m3. Our cells provide superior performance across all duties in rougher, scavenger, and cleaner circuits. Based on in-depth test work, we can design a tailor-made flotation circuit for your plant that will deliver optimized cell volume, froth carry rate, and residence time. OUTOTEC FLOTATION
each cell requires additional energy. Column cells are also mixed tanks due to the flow characteristics of the air and feed slurry. Several investigations have examined the mixing characteristics of laboratory and industrial column flotation cells in mineral applications Dobby and Finch, 1990, Yianatos et al, 2008.
characteristics change from cell to cell. Industrial flotation columns are square or circular, typically 0.5-3m in diameter or side, and 12-15m height. Since their invention, square columns have been marketed commercially by the Column Flotation Company of Canada Ltd. The apparent simplicity

A flotation column could be considered as one of the major breakthroughs in the field of mineral processing in the last decades. Due to an increase in the trend of the use of these type of cells ...
cell design elements As an integral part of a flotation circuit, column flotation is highly effective in producing high-quality product, offering superior recovery of fine materials. Through proper column sizing and design, this technology complements mechanical cells and improves overall flotation circuit performance.

Column cells have been developed over the past 30 years as an alternative to mechanically agitated flotation cells. The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs.
As such, the number of cells are lower and the cells smaller. Column flotation is sometimes used as cleaners. Recycle streams are important to maximize selectivity and thus efficiency. 145-5-38 Rougher-Scavenger-Cleaner Effect Rougher-Scavenger-Cleaner Effect image 145-5-39
