MARCH 2005 LS - ESO NFCA PLC
The residue from the heap leaching processes will be left in-situ. Other types of waste will
be disposed of to a permitted dumpsite.
1.6.4 Location of Plant Sites
In order to take full advantage of facilities like water supply, electricity, traffic, etc, utilize
the resources available efficiently, save investment and production cost; the plants will be
built in different location as follows:
• The oxide ore and vat leach residue heap leach plant will be located in the space which
lies between north of No.4 stockpile and south of the main ore conveyor belt (CV2
• The solvent-extraction and electro-winning plant offices and the other auxiliary
facilities, etc, will be built on the land, which lies to the east of the backfilling plant north of
the open-pit and south of the main conveyor belt.
1.7 Project Expenditure
It is estimated that US$12,001,400.00 will be required to bring the Leach Plant into
It is estimated that the total annual expenditure at full production will be
1.8 Project Alternatives
The following project alternatives were considered:
Transportation of the imported equipment and reagents will either be by road or rail
or both. Indications are that rail transport will be the most convenient and cost
effective transport mode.
Transportation of sulphuric acid from the Acid Plant to the Leach Plant, a distance of
about 500m, will be by pipeline and / or road tankers. Transportation of the acid sold
out will be by road tankers.
Power and water supply
No alternatives were pursued, since the power and water required can readily be
supplied from the existing infrastructure without the need for any expansion to the
Industrial waste disposal
SINO-METALS LEACH ZAMBIA LTD ENVIRONMENTAL PROJECT BRIEF
MARCH 2005 LS - ESO NFCA PLC
No new land will be disturbed for the disposal of tailings from the agitation leaching
as the proposed site for a new dam is already inundated and has been already
assigned for industrial purposes. The empty spaces created by reclamation of the
tailings will be backfilled with successive tailings from new reclamations.
Heap leach residue will remain in-situ in already inundated land in the low-grade ore
stockpiles. No new land will be expected to be disturbed.
Solid waste disposal
The only solid wastes that will arise are the foreign objects such as steel scrap and
timber that have been dumped on some of the dumps. The available alternatives
• Disposal of the timber at a permitted dumpsite.
• Selling the steel scrap for reuse at the foundry or other steel recycling companies
Land use options after rehabilitation
No alternatives were considered for the proposed Plant in isolation, since the Plant
area will be rehabilitated as part of the overall NFCA PLC operations, to be produced
by the consultants contracted to produce the Environmental Assessment.
1.9 The “no project” option
If the construction of the Leach Plant were not to proceed then the socio-economic
benefits associated multiplier effects on the local suppliers and contractors with the
proposed Plant will then not materialise
1.10 Environmental Aspects
1.10.1 Negative environmental aspects
If a project involves a completely self-contained “black box”, then adverse impacts
will only result from the fact that the “black box” will occupy space. Additional
impacts would only result if there were inputs to or outputs from the “black box”.
Therefore, the identification of environmental aspects1 associated with a project’s
• establishing the manner in which it will occupy the site; and
• identifying the inputs and outputs.
In the International Organisation for Standardisation (ISO) Environmental Management System
standards (ISO14001 and IS014004) the mechanisms that can cause environmental impacts are referred
to as environmental aspects and are defined as: “Environmental aspects refer to an element of an
organisation's activity product or service which can have a beneficial or adverse impact on the environment.
For example, it could involve a discharge, an emission, consumption or reuse of a material, or noise.”
