abstract = "The mining sector, nowadays, faces rising
challenges to find suitable practice that are
sustainable for already disposed waste streams
(AMD, flotation tailings and fly ash) [1]. There is a
growing tendency globally to use waste from
various industries to neutralize AMD, which has
both economic and environmental benefits. In
attempt to connect mining waste with concept of
sustainable development in the Republic of Serbia,
several experiments were taken into consideration:
neutralisation of AMD from Bor’s mine with a)
flotation tailings from copper mine Majdanpek
(FJM) b) fly ash (FA) from thermal power Nikola
Tesla (EF) and Kostolac (KOST). All three samples
of alternative product are voluminous, hazardous
waste products, difficult and expensive for safe
deposition, causes environmental pollution (by
spontaneous leaching of useful components, which
causes additional investment in the rehabilitation of
that or reversibly lost compounds that pollutes the
environment, or its dispersion by wind in
surrounding streams and groundwater resources of
drinking water, air or soil and also degradation by
soil erosion) and can affects human health’s if are
not regularly discharged. But its benefits are that
there are free of charge alkaline wastes, suitable to
neutralize the AMD by altering pH, which leads to
precipitation of valuable metal which can be reused,
such as Fe or Cu. The chemical and mineralogical
composition of the initial samples of FJM and FA
was evaluated two standard leaching tests: TCLP
and EN 12457-4, as well as Acid Neutralization
Capacity test. These base materials were shown to
have a large capacity to neutralize acid, making
them a highly effective alternative material for
neutralizing acid mine drainage and eliminating
metals, even better than results of neutralisation
with NaOH, as conventional reagent. According to
the findings the FJM and FA neutralization
experiments precipitated more than 99 % of Al, Fe,
and Cu, 90 % of Pb, and 92 % of Zn. Leaching of
these metals from FJM and FA raises Cd and Mn
concentrations. Additional treatment was
undertaken using hydrated lime to boost the pH to
10 and so offer circumstances for its removal, in
order to reduce the concentration of Mn below the
authorized limits by Serbian legislation. At the end,
as a result of utilizing alternative materials such as
FJM and two FA purified water, safe for release into
the environment was obtained. In this way,
resources are preserved for the future generation,
and the treatment of already disposed amounts of
waste reduces the contamination of the
environment, the emission of toxic metals and the
formation of acidic mine waters.",
