黑龙江科后屯地区矿床分布规律与找矿潜力分析

Analysis of the Distribution Regularity of Ore Deposit and Prospecting Potential in the Kehoutun Area of Heilongjiang

近年来,在黑龙江科后屯地区发现了多处金及多金属矿床。为总结区域成矿规律,研究典型矿床特征,笔者通过对区域地质背景的分析和三合屯西矿化点地质特征的总结,从空间分布和成矿时代两个方面总结了区域矿产分布规律,从地层、火山岩、侵入岩、构造四个方面研究了区域成矿条件。根据研究成果,圈出嫩北农场金Ⅲ级成矿远景区1个,指出嫩北农场至三合屯一带是寻找金的有利地区。

The flotation of iron ore has features of uncertainty, complexity, nonliterary, time lag and eou pling, making it hard to optimize the dosage of collector. The method about the optimal setting of collector dosage based on case--based reasoning （CBR） was presented to optimize the flotation process online. The method was applied into a dressing mill＇s iron ore flotation process successfully and the application results showed that the method is feasibility and effectiveness.
