Could you please send me some links of journals or books for my reference (with authors in it) that explains very details of what's happening when water, sulphide and Oxygen reacts and make AMD, like why acidity can dissolved metals in water? How acidity can dissolved metals in water? How is chemical bonding of metal, water and Oxygen react?, something very detail about Chemistry perspective of Acid Mine Drainage

One of the best places to start would be the GARD Guide. Visitwww.gardguide.com. This free, on-line reference was prepared by a group of engineering and scientific professionals and it was sponsored by INAP, the International Network for Acid Prevention. INAP is a consortium of responsible mining companies who are listed on the bottom of the website home page.

You should be able to find the answers to your questions in the first few chapters of the GARD Guide. References at the ends of the chapters should steer your inquiry in any technical direction you wish.

The GARD guide is a good start, but doesn't have enough references that are essential to answer your question. The GARD guide was meant as a practical guide for practitioners, your questions seem to be academic related.

Good luck!

In addition to the good references above, I suggest you write to Prof Rudy Sayoga at ITB. He has worked with acid-mine drainage (and other mining-related problems) for many years. He can probably direct you to references in Bahasa Indonesia that may be especially helpful to your initial investigations, and I am sure he knows your professors (and they know him), so there may be some good interactions there, too.

Langmuir, D. 1997. Aqueous environmental geochemistry.

Is a good reference along the lines of Stumm and Morgan.

Here is an article that presents the details of acid generation and metal release.

I would recommend attending some university level courses on chemistry for starters.

Aqueous chemistry, aqueous environmental chemistry, geochemistry, applied geochemistry, and even some college level courses like first and second year 'chemistry' courses are all really good for building up fundamental understanding for this subject.

A good start is the global acid rock drainage guide (www.gardguide.com). This site is an international project on ARD which covers the science and the practical aspects. It is comprehensive and fully referenced.
