This document summarizes a student's research project on whether Vale mining company is complying with acid mine drainage standards. The research objectives are to understand what acid mine drainage is and its effects, determine if Vale follows procedures, and suggest ways to minimize impacts. The research questions examine what acid mine drainage is, if Vale follows standards, and if their strategies conform to international standards. The hypotheses are that Vale does not comply with international standards and puts lives at risk.

2. TOPIC
• A RESEARCH TO FIND OUT IF VALE IS COMPLYING WITH
ACID MINE DRAINAGE STANDARDS TO MINIMIZE THE
NEGATIVE IMPACTS, 2017.

3. INTRODUCTION
• Parameters that the Vale Mining uses in treatment of water used in
processing plant;
• Making known the negative impacts caused of Acid Mine Drainage;
• The bad conditioning and treatment of water used in processing
plant;
• Help to mitigate and improve the treatment of the water used in
processing plant.

4. STATEMENT
• Contributes of Mining Industry;
• Treatment and Control of Effluents;
• International Standards;

5. RESEARCH OBJECTIVES
• To understand and know what Acid Mine Drainage (AMD) is
and possible effects on the environment and human life.
• To find out if Acid Mine Drainage (AMD) procedures are being
followed at vale.
• Highlight the negative impacts caused by AMD and suggest the
possible ways or minimization strategies for treatment of AMD.

6. RESEARCH QUESTIONS
• What is Acid Mine Drainage (AMD) and how does it occur?
• IsVale following the Acid Mine Drainage Standards?
• Do vale strategies conform with International Standard of
AMD?

7. HYPHOTESES
• Vale is not complying with international standards;
• Vale is putting people’s lives at risk.

8. CONCLUSION
• Acid Mine Drainage (AMD) cause severe negative impacts to
environment and human health;
• The effluents generated in the company's mineral processing
plant should be treated in accordance with international
standards.
