從上述試驗(yàn)可知，原礦與鏡鐵礦的配比為5∶2時(shí)，所得的鐵精礦品位較高，且回收率也較大。原因是鏡鐵礦硬度大，可以更好地起到擦洗作用，使礦石單體解離度和回收率提高，因此選擇原礦與鏡鐵礦的配比為5∶2進(jìn)行流程試驗(yàn)。流程試驗(yàn)將配好的礦石磨至－.97mm占85.41%，首先進(jìn)行搖床粗選條件試驗(yàn)，條件同3.2.1，對搖床條件所得粗精礦進(jìn)行精選，精選尾礦返回粗選。結(jié)果可知，混合礦經(jīng)過搖床粗選，粗選精礦再經(jīng)搖床精選一次，鐵精礦品位6.15%，回收率52.28%，回收率較其他方案有較大幅度的提高。

使用管道檢測儀對埋地管道進(jìn)行檢測，能在非開挖狀況下，實(shí)現(xiàn)對埋地管道的外防腐層的破壞情況進(jìn)行定性、評估，并能對管道進(jìn)行定位、測深，解決了以前在非開挖狀況下無法檢驗(yàn)的難題，該檢測技術(shù)既可作為新竣工管道的檢測、驗(yàn)收手段，也可對正在運(yùn)行的管道進(jìn)行定期監(jiān)測。地管線的腐蝕原因埋地管線的腐蝕原因主要有：土壤腐蝕、大氣腐蝕和生物腐蝕三種。1土壤腐蝕新疆的土壤干燥，土質(zhì)屬中性至堿性。由于土哈的地質(zhì)條件的影響，沙石較多，土壤空隙大，空氣中的氧極易進(jìn)入土壤，進(jìn)而發(fā)生氧腐蝕。
