Tailings Consolidation Rate

noun

Pronunciation: /ˈteɪlɪŋz ˌkɒnsɒlɪˈdeɪʃən reɪt/

The velocity at which mine waste solids compact and water drains from tailings storage facilities, measured as settlement per unit time under gravitational and seepage forces. This rate determines storage stability, decant water quality, and timelines for site access and earthwork during reclamation.

Plain English

How fast mine waste solids settle and water drains from tailings ponds over time.

Etymology & History

Origin languageEnglish
Roottailings (tail + -ings) + consolidation (Latin consolidare) + rate (Old French rate)
First recorded use1960s
Usage frequencyCommon

Usage

"The tailings consolidation rate of 2 centimeters per month allowed construction on the upper tailings embankment after 18 months of dewatering."

Style guide notes: Always specify units (mm/month or cm/year) and reference soil type when reporting consolidation rates.

Frequently Asked Questions

What factors affect tailings consolidation rate?

Particle size, clay content, initial density, and permeability significantly influence consolidation speed.

Why monitor consolidation rates during reclamation?

Knowing settlement rates ensures structural stability and determines when surfaces are safe for construction or use.

Why Test Candidates on This?

Essential for determining reclamation work schedules and foundation design on consolidated tailings surfaces.
