Water Quality

Developers often associate environmental requirements with additional costs and extended project time frames, in many instances seeing environmental services as a grudge purchase. But what if the opposite was possible? What if building environmental considerations into each Read more... about How sustainable urban design can reduce infrastructure costs

The Century open cut zinc mine at Lawn Hill recently changed ownership from MMG Limited (MMG) to New Century Resources (NCR). Closure planning for the site was initiated by Zinifex, developed further by MMG, and is continuing under the new ownership. The waste rock dumps will be covered with a Read more... about Pit Lake Water Quality Modelling at Century Mine

Awareness of the effects of mining on water quality has existed for several centuries but the need for management measures and consideration of the associated costs to address potentially unacceptable water quality effects has increased in modern times. This has arisen from improved Read more... about Mine Water Liability: Evaluating the Risks and Potential Costs

Closure options under consideration at some sites include backfilling mined-out pits with waste rock. Backfill may include mineralised and non-mineralised waste rock. Following groundwater rebound, flow-through conditions may develop in the pit post- closure. The backfill located in the Read more... about Backfilled Pits – Laboratory-scale Tests for Assessing Impacts on Groundwater Quality

This presentation summarizes a talk given during the inaugural workshop of the Cave Mining Forum.

This presentation will briefly discuss how cave mine closures can differ from typical underground mine closures. There is limited Read more... about Caves Complicate Closure

Brine extraction for surface process and recovery of potash, lithium and industrial salt requires the application of traditional hydrogeological theories to hyper-saline solutions. Such Read more... about Lithium Brine Projects: there is a resource, but is there a reserve?

During active mining and post closure, the control of water requires prudent site management to firstly minimise the generation of minewater and secondly to treat where necessary. In order to reduce associated treatment costs in the long term, artificial wetlands have gained acceptance, Read more... about Passive Treatment: A Walk Away Solution?
