It is pointed out that through absorbing the quintessence of both chlorination refining and sulfur acid hydrometallurgical refining processes , present traditional refining technology should be transformed so as to reliably transit to completely - hydrometallurgical refining of high grade nickel matte 指出，现行高冰镍精炼工艺的改造应吸取氯化精炼和硫酸湿法精炼两种工艺的长处，稳妥地向高冰镍全湿法精炼过渡。
Based on the summarization of high grade nickel matte refining techniques both at home and abroad , and in the light of practical production of the complex , the advantages and shortcomings of sulfur acid hydrometallurgical refining technology of high grade nickel matte are emphatically set forth 在综合国内外高冰镍精炼技术的基础上，结合金川有色金属公司的实际情况，重点阐述了高冰镍硫酸湿法精炼和氯化精炼工艺的优缺点。
Firstly , a coarse forecasting model based on only the primary influencing factor ( that is the weight of iron in matte ) is built using linear regression analysis , then , an error compensating model based on other influencing factors is built to improve the result of forecast 首先应用线性回归技术建立了仅考虑主要影响因素（铜统含铁量）的粗略预报模型，而后，应用神经网络技术建立了考虑到多个次要影响因素的误差补偿模型，从而改进预报效果。
