Exploration: What Reserves and Resources?

摘要: The Exploration Node focuses on the search for assessment and quantification of phosphate reserves resources in relation to geopotential (i.e., undiscovered resources). encompasses all aspects predevelopment stages deposits from initial discovery involved feasibility studies required obtain funding development a mine. producing rock (PR) can be broadly defined terms technical economic feasibility. In order potential ores classified as reserves, consideration must given issues grade, quality, operating, investment costs which include accessibility availability financing. Details about these considerations are often proprietary, making it difficult publically assess resource picture. Phosphorus is eleventh most abundant element. P essential life cannot substituted by other elements food production. knowledge resources, accessibility, scarcity phosphorus may depend available technologies finally an question. We discuss number parameters indicate whether increasing concern. These resource/consumption ratio, Hubbert-curve-based peak predictions, trends ore new rates, pricing they important understanding exploration efforts. further estimates actual reserves. reserve dynamic will increase some time. Nevertheless, at time long-term future, there such point that mined becomes less economical than conservation recovery.
