Abstract
The utility model provides a grinding new medium, wherein a steel ball grinding new medium is filled to replace steel ball grinding medium in a ball grinding machine. The grinding new medium has the beneficial effects that the grinding new medium increases contact and scrubbing between mineral and media to enable grinding to be more sufficient, thereby intensifying the monomer degree of dissociation of the mineral, and enabling the minerals to have more floatability, the drug consumption can be reduced, the molybdenum concentrate impurity copper contents can be lowered, and the taste of molybdenum concentrate and copper-molybdenum sorting integrated reclaiming indexes can be improved.
Description
Technical field
The utility model relates to a kind of ore grinding new medium of ore dressing industry, the milling medium that uses when relating in particular to copper molybdenum assorting room
Background technology
During copper molybdenum sorting at present, one section coarse concentrate regrinding process using steel ball is as milling medium.Be a contact form between milling medium and the mineral, grinding efficiency is low, and the mineral scrub effect is poor, and the ore grinding effect is not obvious, causes copper molybdenum sorting recovery index poor, and molybdenum concentrate grade hangs down and impurity copper content height, influences the technical-economic index of molybdenum concntrate deep processing.
Summary of the invention
The purpose of this utility model just provides a kind of ore grinding new medium.To increase rough concentrate degree of dissociation of mineral monomer in the assorting room, strengthen the scrub effect of mineral, the floatability of restore target mineral.To reduce the molybdenum concntrate production cost, reduce molybdenum concntrate impurity copper content, to improve molybdenum concentrate grade and the comprehensive recovery index of copper molybdenum sorting.
The utility model is to adopt rod iron milling medium instead of steel ball milling ore deposit medium, and described rod iron milling medium is cylindric, and its specification is: diameter is 12mm, highly is 25mm, is that the line face contacts between new medium and the mineral.The contact-making surface that has increased between mineral and the medium makes friction more abundant, thereby increases the liberation degree of minerals of target mineral, guarantees the mineral scrub effect, increases the floatability of mineral, reduces reagent consumption, improves the comprehensive recovery index of copper molybdenum sorting.
