Study on General Situation and Analysis of Supply and Demand of Global Phosphate Resources
摘要
Abstract
The global phosphate resources are abundant , but the distribution of them is uneven . The supply center of phosphate resources gradually transfers from North America and East Asia to North Africa and the Middle East .The global average grade of phosphate ore is 19 .61%, and the ore dressing recovery is 63 .01%.According to the "Three Indexes Survey" of China , the average feed grade of phosphate ore is 19.4%, the ore dressing recovery is 89.97%, indicating that the development and utilization of phosphate ore is relatively advanced in China .Compared with the global average production cost ( 57 $/t ) , the production cost in China ( 38 $/t ) is relatively low, but it shows an upward trend .Due to the exploration of phosphate ore resources in Morocco , Saudi Arabia and other countries , the global market provides more phosphate ores than the de-mand, and this trend will be maintained .Under the influence of multiple factors , i.e., the mining market recovery, resource supply, food prices, profit margin, the global phosphate prices will pres-ent a modest rise rather than a sharp rise in the short term .关键词
