2. 分别考察石煤常压氧化酸浸和加压氧化酸浸过程中的钒浸取率。
The leaching rates of vanadium of oxidizing acid leaching at atmospheric pressure and oxidizing acid pressure leaching were studied separately by contrasting conclusion.

3. 建立了常压预浸合金硫化镍矿的氧化浸出数学模型，并进行了验证试验。
The leaching performance of the low grade molybdenite from Jinduicheng Mine is investigated by both bioleaching and chemical oxidation leaching process.
The process is acid adding pre-leaching at normal pressure, pressurized oxygen leaching to leach out base metals and filtering separation to obtain solid noble metal concentrate.

5. 在没有活化剂存在和常温常压条件下，即使经过长时间的水浸，无机非金属材料也不会凝胶和固化。
In the absence of activator existence and normal temperature and pressure conditions, even after a long period of flooding, inorganic non-metallic materials will not gel and cure.
