1. what function do the sodium sulpide work on the flotation process about sodium sulfide?

1、sulphurize Non-ferrous metal oxide 2、Suppress all kinds of sulfide 3、Take off the collecting agent when deal with mixture of sulfide ore concentrate 4、Adjust ions ingredients in Ore mixture

2. How long will it take to get the approved export licence of sodium sulfide for each clients since you receiving our endusr's documents ?

It usually takes 22 working days from us submitting the application documents, that means 22 days + 2 days(filling paper) = 25 days

3. what's the key factor to influence the color of sodium sulfide flakes?

the ferric is the first and last word, second sulphur, and the just time of making process.

4. What do your firm use as raw Material to do Sodium Sulfide (Na2S) synthesis?

barite (main content is BaSO4), glauber salt and coal

5. What role does the sodium sulfide play as the vulcanizing agent in the non ferrous metal oxide ore?

sodium sulfide can be as a vulcanizing agent for non-ferrous metals oxide ore. but non-ferrous metals oxide ore can’t be collected directly by xanthate. if we make non-ferrous metals oxide ore effect with sodium sulfide before using xanthate flotation, then it will have thin film on the mineral surface , then it will be collected by xanthate.

6. How to choose sodium sulfide purity according to its ore properties?

if the mineral oxidation rates of sulfide ores is low, it can use some. If it is high, it can use more.Generally the amount of mineral per ton is in dozens of grams to 1kg. But it can use dozens of kilograms of sodium sulfide 60% . For instance a copper oxide, the amount of sodium sulfide 60% is 4-5kg/t when it is in the vulcanization process, then it gets satisfactory results.
