Secondary Mineral Formation
nounPronunciation: /ˌsɛkənˈdɛri ˈmɪnərəl ˌfɔrˈmeɪʃən/
The precipitation and crystallization of new minerals resulting from chemical weathering of primary mine minerals and interaction with water and oxygen. These secondary minerals can be toxic (like jarosite) or beneficial (like iron hydroxides) depending on their composition and behavior.
Plain English
New minerals that form when mining waste reacts with water and air, sometimes creating additional pollution problems.
Etymology & History
Usage
"Secondary mineral formation in the tailings impoundment produced jarosite, which continued to release acid decades after mining ceased."
Style guide notes: Name specific secondary minerals when discussing particular sites; avoid generic references.

Frequently Asked Questions
What secondary minerals form in abandoned mines?
Jarosite, iron hydroxides, gypsum, and schwertmannite form from sulfide oxidation and metal precipitation in acid mine drainage.
How does secondary mineral formation affect reclamation?
Continuing mineral precipitation can produce additional acidity and trace metals long after mining, complicating long-term water treatment.
Why Test Candidates on This?
Secondary mineral formation is relevant for advanced reclamation courses and specialized geochemistry assessments.
