求翻译：在一定用量范围内，随着油酸钠用量增加赤铁矿、磁铁矿回收率逐渐增加而石英回收率一直为零。可见油酸钠对除石英以外的两种纯矿物均有良好的捕收性能。是什么意思？

Sodium oleate in a certain dosage range, with the increase in hematite, magnetite recovery is gradual increase in quartz recovery rate has been zero. Sodium oleate on the outside of the quartz two pure mineral. Have good collector performance.

To a certain usage, as oil-grained hematite that increased sodium consumption rate, magnetic iron ore and quartz rate increase has been to zero. It can be seen in addition to sodium acid than quartz of the two pure mineral that has good fishing for performance.

But in certain amount used scope, along with the sodium oleate amount used increase hematite, the magnetite returns-ratio increases the quartz returns-ratio always is gradually the zero.Obviously the sodium oleate to has besides the quartz two kind of minals good catches receives the performance.

Within a certain range, with sodium oleate gradual increase in dosage increases recovery rate of Hematite, magnetite and quartz recovery rate is zero. Sodium oleate on two pure but the quartz mineral collector of good performance.
