[求助] 求助（修改）英语语法

Experimental melting temperature is 1200 ℃, while the temperature of Fe and Zn could be reduced is above 1400 ℃, and the temperature of Si could be reduced is above 1800 ℃. So the oxide of above metal are not reduced, just formed the slag. The affinity between Cu, Bi and oxygen are very small, so the most be restored into the crude lead. While the affinity between As, Sb, Sn and oxygen are greater than the lead, however, their solubility are great in the lead, it is easy to be restored into the crude lead. But these metals have low levels, and the purity of lead in recycled metal is approximately 97.2%, which meets the general industrial needs.

Experimental melting temperature is 1200 ℃, while Fe and Zn need a temperature above 1400 ℃, and  Si needs a temperature above 1800 ℃ to be reduced. Therefore the oxides which are not reduced under this condition , are turned into slag. The affinity between Cu, Bi and oxygen are very weak, so most of these will (not??) be partitioned into the crude lead.  While the affinity between As, Sb, Sn and oxygen are greater than that of lead and oxygen , however, they have good solubility  in molten lead, and are easily partitioned into the crude lead.  Since these metals only present in low levels, and the purity of lead in recycled metal is approximately 97.2%, which meets the needs for general industrial purpose.  意思表达得不清楚
