The River Murray, seawater and acid drainage
water composition applied to the treatment plots is shown in Table 1.
Contract awarded for Jinshan acid drainage
from the Gold King, about 550 gallons per minute, currently is being treated using a temporary plant run by the EPA for an estimated $16,000 a week.
The government's decision came after the local community protested against the mine, concerned about acid drainage
, heavy metals and the use of cyanide in the mining process, risking the contamination of major water catchment areas.
The series is produced by the Acid Drainage
Technology Initiative-Metal Mining Sector, a group of volunteers from state and federal governments, academia, mining companies, consulting firms, and other interested parties who are involved in the environmentally sound management of metal mine wastes and drainage quality issues.
The input of acid drainage
from these mining areas, most of them without rehabilitation, leads to modifications in the physical-chemical characteristics of the streams.
The other is the acid drainage
that gushes out of the mine opening.
Investigating water management and acid drainage
issues from an environmental risk perspective
Such an approach can ensure that acid drainage
does not develop, while allowing the land to be used for a productive purpose, such as the growing of eucalypt trees for essential oils and firewood, and the creation of native seed farms.
The Society's Acid Drainage
Technology Initiative--Metal Mining Sector (ADTI-MMS), based in Colorado, identifies, evaluates, develops, and disseminates information about cost-effective, environmentally sound methods and technologies to manage mine wastes.
If pyrite is present, acid drainage
may result [1, 2].
For the past 2 years, Ray Bryant, soil scientist and research leader, has tested gypsum byproduct, residual material from treating acid drainage
from coal mines, and steel slag.
