Midas美国MIDAS-S-CO2二氧化碳（CO2）霍尼韦尔降低成本、提率
在等式右边各参数中，精矿品位β基本不变，精矿价格P在一定时期内也基本上为定值。因此p-,P可以参考生产实际取定值。随着入磨品位的降低，矿石可磨性变差，导致磨选成本有所升高，但为计算方便，仍可参考生产实际将c取为定值。值得注意的是，金属回收率ε是原矿品位α的变量，ε随a的降低而降低，a越低，对ε的影响就越大。湿选金属回收率不能参照正常生产数据取值，而应由低品位矿石根据试验确定。同时也应注意到，近几年随着铁精矿价格的大幅上扬，回收界限也应相应降低。响预选分选效果的主要因素回收界限更多地对于单个矿粒而言的。在生产实践中，由于受多种因素的影响，回收界限比较容易模糊：部分应予回收的矿石有被抛弃，造成金属流失;还有部分该抛弃的废石混入预选精矿中，增加磨选费用。1矿石粒度对分选效果的影响任何一种选矿设备都有其适于选别的矿石粒度。在确定的选矿设备和工艺条件下，给矿粒度是影响选别效果的主要因素之一。对于给定的磁滑轮或大块干式磁选机(包括转速等参数)，回收磁性矿粒所需比磁力F磁是随矿粒粒度的变化而变化的，粒度越大，所需的比磁力F磁也就越大，矿粒的磁铁矿含量也应越高。

制造阀门零件材料很多，包括各种不同牌号的黑色金属和有色金属及其合金、各种非金属材料等。制造阀门零件的材料要根据下列因素来选择：工作介质的压力、温度和特性。该零件的受力情况以及在阀门结构中所起作用。有较好的工艺性。在满足以上条件情况下，要有较低的成本。部分阀体、阀盖和阀板（阀瓣）的材料阀体、阀盖和闸板（阀瓣）是阀门主要零件之一，直接承受介质压力，所用材料必须符合“阀门的压力与温度等级”的规定。
