The copper concentrate mineral phase transformations for different wet fine-grinding time intervals was characterized by x-ray powder diffraction and shown in Fig. 2a. The obtained XRD results indicate that the dominant copper phases changed from chalcopyrite and bornite at 0 min to covellite and copper sulphate at 120 min, indicating that oxidation reactions occurred during fine grinding.
The system is rigged against you. The article I'm excerpting here is posted at CNN, a mainstream news site. This is not fringe thinking. This is a conventional view of how economics is supposed to work. I'm not even particularly singling out this one essay, just using it as an example.

From a strictly economic standpoint, fine pulps are objectionable on the grounds that they cost more money to produce (high grinding cost), and more money to treat (high reagent consumption). The higher cost of grinding to produce fine pulps is well known, and is generally advanced by practical operators as the argument against fine grinding.

Fine grinding grains should be avoided in cattle diets because fine-ground grains, "fines", quickly ferment in the rumen. Becca Stokes, KWS feeding nutritionist, recommended at Loran Steinlage's field day not to exceed more than 6 percent fines in cattle feed to prevent acidosis. If I am going for a finer grind how can I keep the dust down?
Although flotation recovery, and hence NSR, increases with fineness of grind, it is evident that there is no economic benefit in grinding finer than 105 microns. Even this fineness will probably by beyond the economic limit because of the additional capital cost of the grinding equipment required to achieve it. Figure 4..
For the processing of non-metallic minerals, one is to remove impurities and improve the purity of the product; the other is to reduce the particle size of the product to varying degrees. In the process of reducing the particle size of the product, the choice of grinding equipment is very important, which directly affects the utilization rate of minerals, production costs, product quality and ...

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).
