It was found that weighting by cross sectional area was the most appropriate method to determine the specific surface area.

同时还讨论了气泡特征与浮选操作条件之间的关系，为计算机在线控制浮选过程建立基础。

Accordingly, want to realize Dong Anshan to contain the effective depart of content of the iron ore in carbonate iron ore and quartz, if where,the key is before turning over floatation, go out siderite depart beforehand, or the floatation drug that find can effective activation or restrains siderite.

因此，要实现东鞍山含碳酸盐铁矿石中铁矿物和石英的有效分离，关键是如何在反浮选之前预先将菱铁矿分离出去，或找到能有效活化或抑制菱铁矿的浮选药剂。

The primary reason found why sillimanite is difficult to separate from quartz is that Fe 3+ and Al 3+ can activate the floatation of quartz in a neutral or slightly alkaline medium with sodium oleate as a collector.

结果表明：采用油酸钠为捕收剂，Fe3+和Al3+在中性或弱碱性介质中对石英浮选有很强活化作用，从而使硅线石和石英浮选分离困难。

In order to increase flotation efficiency and selectivity, the method of pre-ultrasonic processing slime before flotation has been proposed.

为了提高煤泥浮选的效率和选择性，提出了在浮选前对煤泥进行超声波预处理的方法。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
