CJ Filter is a professional provider for filter press solutions and systems for the mining and mineral, metals refining, chemical industries globally.
The difficulties for filtration of Iron concentrates and tailings
The proven total reserves of iron ores in China are relatively abundant, but the reserves of high-grade iron ore are rare. The iron ores mainly belong to low-grade ores, possess 80% of the total proven reserves of iron ores. In addition, there are plenty of complex ores with multiple elements. It leads to the finer grinding of iron ores in multi-stages for reselection, the finer particle for iron concentrates and tailings. The CJ air-flow high efficiency can perfect meet the requirements for low cake moisture and high capacity.

Some successful stories for filtration of iron concentrates / tailings
| A technology company in Tianjin | |
Application | Iron slags | |
Cake Moisture | 14-15% | |
Filtration Area | 410sq.m | |
Unit Capacity | 120t/d | |
Washing Efficiency | Save at least 50% energy and water. | |
The customer use CJW washing filter press for the hydrometallurgy project. The cake moisture is 4%-15%. Filtration rate is 24kg/㎡h. After washing by 1.5times water, the comprehensive recovery rate is very high. At least 50% energy and water consumption is saved compared to original process. | ||
| An iron plant in Vietnam | |
Application | Iron concentrates | |
Cake Moisture | ≤10% | |
Filtration Area | 580sq.m | |
Unit Capacity | 1000t/d | |
It's red iron ore which is difficult for filtration.The cake moisture is ＞15% for the test of membrane filter press. When the customer used CJ series filter press, the cake moisture is ≤10% and can be processed for smelting. The customer extremely reduced the maintenance costs. | ||
| A regenerated resources sales company in Sanmenxia | |
Application | Iron concentrates | |
Cake Moisture | ≤8% | |
Filtration Area | 512sq.m | |
Unit Capacity | 1200t/d | |
The customer mainly processes the smelting slags produced by smelters. The daily capacity is 1000ton. They originally used ceramic filter press for the filtration with a cake moisture around 16%. In addition, 40000 Chinese Yuan of Nitric acid would be required for washing monthly, leading to great costs waste and environmental pollution. After technical reform, the customer used 2sets of CJ air-flow high efficiency filter presses for the filtration of iron concentrates. The moisture for iron concentrates is ＜8% which met the requirements for production in site. | ||
| An environment protection company in Jiangxi | |
Application | Iron slags | |
Cake Moisture | ＜45% | |
Filtration Area | 210sq.m | |
Unit Capacity | 180t/d | |
Washing efficiency | >75% (the content of soluble zinc reduced from 18% to 4.5% with a moisture <45%) | |
The customer used CJ air-flow high efficiency filter press for the filtration of iron slags with perfect washing efficiency >75%. We help customer greatly shorten production process, save production costs and increase its capacity. | ||
| A copper company in Tibet | |
Application | Flotation Iron Concentrates | |
Cake Moisture | ≤10% | |
Filtration Area | 328sq.m | |
Unit Capacity | 600t/d | |
The customer used CJ air-flow high efficiency filter press to filtrate the iron concentrates by flotation. The cake moisture is less than 10% even at the high-altitude area and with ultra-fine particles. The unit capacity is over 600Ton per day. | ||
| A trading company in Sichuan | |
Application | Iron concentrates | |
Cake Moisture | ≤10.5% | |
Filtration Area | 512sq.m | |
Unit Capacity | 1000t/d | |
In order to raise the grade of the iron concentrates, the concentrates would be crushed and grinded finely to -400mesh 98%. The original ceramic filter press in site could not fit for finely application. After much work, communications, tests and verifications, the customer finally selected CJ air-flow high efficiency filter press for the filtration. The cake moisture was extremely low and greatly saved transportation costs. | ||
