Economic Potash Fertilizer Rate Recommendations
<p>This thesis is comprised of two studies that estimate profit-maximizing potassium (K) fertilizer application rates for various crops across different time periods. Estimation of profit-maximizing fertilizer-K rate (K*) for both studies considered the initial soil test level of K (STK) and yield …

Investigation of Polymeric Reagents for KCI Collection Furing Potash Flotation
Potash is an integral component of agricultural fertilizers, and remains in high demand throughout the world. Presently, the majority of potash refinement is achieved via froth flotation, which is typically facilitated by tallow amine collectors. Recent developments in mineral extraction have begun …

An Auto-Picking Algorithm For The Detection of Clay Seams In Potash Mines Using GPR Data
Potash mines can be in operation for up to one hundred (100) years. Maintaining a stable mine roof is critical for the safety of current and future underground mine operations. Visual clues on side walls, combined with the historical knowledge of the ore formation in a particular region, provide a …
