Similarly, it is 80 hypothesized that different species such as those used in this study have different demand 81 from the rhizosphere soil, resulting into changes in the rhizosphere mineral elements 82 concentration and their respective plant uptake. 83
Read MoreThe results also showed significant differences in rhizosphere concentration of minerals between and among the five cowpea genotypes, with cv. Sanzie consistently indicating much lower levels of P and Ca as a result of higher root uptake, which was evidenced by the higher tissue content of P, K, Ca, Mg, Na, S, Fe, Zn, Mn and B in cv. Sanzie.

The lowest mean Ca concentration (1.80 g/kg) was detected in the Luga genus, while it is noteworthy that the highest mean Ca concentration (26.8 g/kg) was found in the green seaweed Ballia.

It consists of reserves and is largely defined by its grade and its tonnage. Enrichment and concentration processes are greatly influenced by geology. Each element and each commodity has a specific geologic association. This leads to a very

The concentration of the element or compound of interest in an ore is referred to as the grade of a deposit. To be graded, however, a mineral deposit must attain a minimum size, because no matter how high its grade, a

A mineral deposit is a body of naturally occurring geologic material, from which by concentration, enrichment or other processes, a commodity can be mined profitably,
Read MoreMany different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
