We are a clean mining innovation laboratory.

Terra CO2 Technologies (Terra) is currently developing methods of addressing two major environmental problems: acid rock drainage (ARD) from mining, and excess atmospheric CO2.

Our technology aims to allow safe "dry-stacking" of potentially acid generating (PAG) tailings, and tailings at risk of metal leaching. Ideally, we will displace the need for tailings dams in many new sites, especially where dry-stacking of filtered tailings has previously been problematic.

Terra’s technology also has implications for greenhouse gas (GHG) reduction:

  1. Conversion and long-term storage of CO2 is achieved by synthesizing stable metal carbonate compounds.
  2. Drastic reduction in the perpetual lime consumption needed for water treatment at mine sites. Production of lime is extremely greenhouse-gas intensive and therefore eliminating lime use is desirable.

In 2018, Terra is rapidly advancing bench-top research and proof-of-concept demonstrations to prove the economic and environmental viability of one recently patented process, and new complementary technologies.

Acid Rock Drainage

By converting reactive mine wastes to a stable form, Terra’s technology can reduce or eliminate ARD runoff from mine operations. Terra’s initial target is the Canadian mining industry, but we aim to scale globally.


Terra's technology reacts CO2 gas with components of waste metal sulphides to precipitate stable metal carbonates, thereby sequestering CO2 and buffering potential ARD.

CO2 footprint is also reduced by avoiding lime consumption.
