Mineral uptake is the natural process in which all the essential minerals enter the plant's cellular material, typically following the same pathway as water. The uptake of mineral nutrients occurs at both the roots and the leaves. The process of uptake or transport of mineral nutrients is carried out by the plant cells in two different ways:

Moreover, two models were developed to use ceramic balls instead of cylpebs as fine-grinding media in the wet tumbling mill based on the ball size and the ratio of the total mass of cylpebs. Cylpebs can be replaced by ceramic balls with 1.16–1.75 times the diameter of cylpebs, taking up only 76%–83% of the total weight of cylpebs.
