| 摘 要： | 从资源保护和优化利用的角度出发,比较了中国、美国、摩洛哥三国磷矿石的储量、品位、重金属含量、矿产集中度、运输距离等,发现摩洛哥磷矿资源具有极强的优势,而美国资源也要优于中国。在比较了矿产开发规模、回采率、产量、成本、可利用年度等指标后,发现美国与摩洛哥各有优劣,而中国明显落后。根据磷肥生产量估算,2003年中国磷矿实际消耗量达到10558×104t标矿。根据现有开采水平和消费量估算,世界磷矿可以满足100年内的需求,但是中国P2O5≥30%的富矿资源仅能利用到2014年,提高回采率可能会达到2022年。中国磷矿资源开发策略欠佳,浪费严重、经济效益低下,导致远景供应堪忧。针对以上问题,提出了我国磷矿资源合理利用的若干建议。 |

| Abstract: | Focusing on protecting the resource and enhancing its utilization, thi s article compared the reserves,grade,heavy metal content,centralization degree of reserves and transport distance of the phosphate rocks in China,USA and Moroc co.It is found out that Moroccan phosphate rock resources have extremely strong advantages,and the American resources are also superior to China.Comparsons of t he mineral production scale,recovery rate,production,cost and sustainable utiliz ing years revealed that USA and Morocco were superior in these aspects to China. It was estimated that the phosphate rock production in China had exceeded 40 mil lion tons (47.2 million tones in 2003) according to the phosphorus fertilizer pr oduction,which was the highest in the world.If the recovery rate was considered, more than 100 million tons might be exploited in 2003.That means 58.4 million to ns of phosphate rock were wasted.The phosphate rock all over the world can meet the demand of 100 years,but in China if no measures were taken to improve the te chnology of mining and to cut down the wastage,the phosphate rock which contains more than 30% of P2O5 would be used up in 2014.However,if the recovery rate was improved,it can last to 2022.With the exhaustion of the phosphate rock 20～30 y ears later in USA and China,Morocco will become the biggest phosphate supply cou ntry in the world.Despite the advantage of the heavy metal,i.e.,the low cadmium content,China's phosphate rocks are facing a gloomy future for its low,efficienc y utilization strategy. To the above question,this article has proposed several suggestions for the rational utilization of the phosphate rock resource in China . |
