The process of treating acidic water generated from sulfide mineral oxidation in abandoned mines through chemical or biological means to raise pH levels. This treatment prevents environmental contamination and reduces metal leaching into surrounding ecosystems.

Plain English

Treating acidic water from mines to make it safe by raising its pH level.

Frequently Asked Questions

What causes acid mine drainage in abandoned mines?

Sulfide minerals oxidize when exposed to air and water, producing sulfuric acid that leaches metals.

What materials neutralize acid mine drainage?

Limestone, lime, and alkaline materials raise pH; biological treatments use sulfate-reducing bacteria.

Why Test Candidates on This?

Essential for assessing remediation engineering competency in mine reclamation projects.
