The Lasail mining area (Sultanate of Oman) was contaminated by acid mine drainage during the exploitation and processing of local and imported copper ore and the subsequent deposition of sulphide-bearing waste material into an unsealed tailings dump. In this arid environment, the use of seawater in the initial stages of ore processing caused saline contamination …

For most plant species, the majority of absorbed lead (approximately 95%) is accumulated in the roots, and only a small fraction is translocated to aerial plant parts (Kumar, Smita & Cumbal, 2017). In this study, from the total Pb in the plant, 88.7% was accumulated in …

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper …

Acalypha wilkesiana. One of the prettiest South Florida shrubs is copper plant - or "copperleaf" - with its striking, brightly-colored leaves. Each leaf is different, like a miniature masterpiece of nature. Basic varieties come in several different colors - red, pink and white. The red is a rusty mix of coppery red with bright pink accents.
