Abstract：Ferronickel is an important raw material for the production of stainless steel and the impurity element in ferronickel must be controlled strictly. High content of impurity element copper would cause hot brittleness. The impurity element copper removal from ferronickel was systematic studied by adding copper removal agent FeS. The effects of FeS adding amount， the carbon content and initial copper content in ferronickel， experimental temperature were investigated. The results show that the copper removal rate improves with increasing FeS adding amount. Higher the carbon content and original copper content in ferronickel promote the reaction of copper removal. When the carbon content is more than 1% in ferronickel， the copper removal rate does not rise significantly with increasing the carbon content. When the experimental temperature is higher than 1 500 ℃， the copper removal rate can increase but the growth is little.
