Case study: Zinc in the environment — Science Learning Hub
The form of zinc will determine its toxicity, with free zinc ions (Zn 2+) being the most available and toxic form to organisms. Once released in the environment, zinc behaves in different ways depending on the characteristics of the environment:
Surge in global metal mining threatens vulnerable ecosystems
We pave the way for in-depth local studies and future assessments of the cumulative magnitude and transmission of impacts, and summarise how mining companies and policies can contribute to impact mitigation. In order to gauge the potential impact of mining on ecosystems, we focus on ecosystem vulnerability.

Embracing automation for feeder control
A common misconception surrounding automated feeder control is the notion that higher speeds equal increased throughput. Contrary to this belief, optimal feeder control maintains a steady pace. Meaning that a controlled feeder can result in higher throughput by maintaining a more constant pace — as opposed to forcing rapid feeding.
