摘　　要：硫和磷是铬矿石中常见的伴生元素,在铬铁冶炼过程中需要控制硫和磷的含量以降低其在不锈钢产品中的含量,避免对不锈钢产品质量产生影响,在冶炼过程中硫、磷可通过废气、废水、废渣污染环境和影响人体健康。因此对从不同国家进口的铬矿石中硫和磷含量进行统计分析,主要研究南非、伊朗、土耳其、阿尔巴尼亚、巴基斯坦、阿曼、津巴布韦、菲律宾、印度、阿联酋、马达加斯加等不同国家进口的铬矿石中硫和磷含量的分布情况,为进口企业生产提供技术支持,评估其在冶炼过程中对环境污染的风险,对进口铬矿石中有害元素的评估提供技术参考。The Sulfur and phosphorus are the accompanying elements in chrome ore. They can influent the property of ferroalloy, so their content in ferrochromium must be controlled, they also can pollute the environment atmosphere and water supplies during the production process. This paper analyze the sulfur and phosphorus content in chrome ore imported from different countries such as south Africa, Iran, turkey, Albania, Pakistan, Oman, Zimbabwe, Philippine, India etc Some sulfur content in chrome ore imported from south Africa, lran, Oman, Philippine are higher than other countries, over higher than the requirement for the smelting grade chrome ore, the highest content is 1.966 % .The phosphorus content in chrome ore imported from south Africa and Philippines is higher than other countries, such chrome ore contain high sulfur and high phosphorus can lead to the risk of environmental pollution.
