The article presents research on the comminution of copper ore in a self-constructed mill using high-pressure water jet energy to investigate the usefulness of such a method for comminuting copper ore. As a result, ore particles are obtained that are characterized by appropriate comminution and a significant increase in their specific surface, in turn allowing for potential further processing ...
Read More2017-8-1 · Comminution is the breaking of larger rocks into smaller ones through crushing, grinding, or other processes. In copper mining, it is used to crush the ore to a fine powder. In this powder form, froth flotation tanks can be used to separate the copper concentrate from the gangue (the remainder of

Read More2021-3-15 · In this presented work we stood before the challenge to create a beater mill for copper ore comminution based on the design of one milling lignite. The motivation was to combine the brittle behaviour of the copper ore’s crystal-like structure with the high energy impact of the beater mill to reduce the energy consumption of the comminution ...
Read More2020-8-25 · To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2.
Read MoreThe process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer ...
