Some Methods of Reducing the Beneficiation Ratio

Beneficiation ratio is the ratio of the ore concentrate weight and the elected fine concentrate, which is the Chrome Ore Beneficiation Plant raw ore concentrate weight an average fine concentrate required. The size of beneficiation ratio reflects the utilization level of resource and beneficiation costs. Therefore, study how to reduce the beneficiation ratio has a very real sense. Reduce beneficiation ratio can be decided from the beneficiation ratio’s three elements: the original, fine and tailings grade, to itemize and improve the ore grade and the magnetic iron share and lower grade tailings, so as to achieve the beneficiation ratio of grinding election system.

(1) Improve the raw ore grade, stabilize the magnetic iron share. Based on the production of geological exploration data, you can optimize the stope blasting design and be reasonable with mine, control the ore grade of stope, reduce the share of the ore grade and magnetic iron fluctuation. Another, optimize the dry separation operations of crushing process, early throw out the surrounding rock and low grade, low share of magnetic iron ore, and improve the grade and magnetic iron share of total iron ore into the mill to create the conditions for lowering the beneficiation ratio and reducing reactive grinding and separation consumption.

(2) Stabilize concentrate grade. Fast, accurate and reliable detection of the concentrate grade plays an important role in knowing the on-site production well. You can use the iron slurry online grade analyzer to timely and effectively detect the fine concentrate grade. Track the ore quality and ore properties, again have the ore blending after the mining and before the mill election, to the difficult dressing or easy beneficiation, you should adjust it in advance to avoid concentrate quality fluctuations.
