2.1 Environmental action Plan (EAP)

The design of the proposed Leach Plant is such that its potential to cause adverse

impacts will largely be minimized or eliminated by means of in-built features e.g.

bunding to contain spills, recycling of process water to increase plant efficiency, high

level of automation for process control etc. However, due to the hazardous nature of

the operation, an incident free regime is not feasible, hence specific additional

environmental management measures to mitigate adverse environmental impacts

are discussed in table 8.

General good environmental management practices will be ensured through

adherence to the approved environmental management measures.

2.1.1 Construction Phase

The construction of the proposed Plant will be managed in accordance with the

approved principles.

2.1.2 Operational Phase

The Leach Plant will be operated in a manner that ensures environmental

protection as per modern design concepts.

Other activities that are of direct relevance are the following:

• Environmental Monitoring Plan

• Auditing and Reporting Plan

• Capacity Development and Training Plan

• Emergency Preparedness and Response Plan

2.1.3 Rehabilitation and Decommissioning

The rehabilitation and decommissioning of the processing facilities at Sino-Metals

will be incorporated in the decommissioning and closure plan for NFCA PLC which

will be covered in detail in the Environmental Assessment (currently under

production). The proposed Leach Plant will consist of relatively minor additions to

these facilities and will not significantly alter the approach to or the cost of

rehabilitating and decommissioning the processing facilities when the processing

operations at Sino- Metals Leach Zambia Ltd and NFCA PLC Chambishi Mine

eventually cease.


2.2 Safety

The proposed copper hydrometallurgical plant at Chambishi Mine will strictly conform to the Mine

Safety Regulations as required by Zambian government, and the principle of “Safety First”

precaution will be followed. In principal personal protection should be the last option / precaution

to protect workers from health damage. The plant has been designed to eliminate or minimize all

forms of anticipated hazards. Personnel will be provided with protective clothing and equipment.

Personnel working in high dust areas should have dust mask, or respirators. Personnel working in

places with noise levels over 85dB(A) such as the Crusher Section will be provided with hearing

protection devices. In addition, efforts to shorten the working time in the high noise level

environments will be pursued.

The following safety and loss control precautions will be carried out:

Safety precautions - Construction and Operation

Personnel will be provided with suitable protective equipment such as overalls, coveralls, and

work suits, foot protection, head protection, hand protection, face protection, hearing protection,

specialized protection etc. to ensure the safety of the personnel. Operators of the plant and

various pieces of mechanical equipment will undergo training in order to operate in accordance

with the established operational procedures.




All the operating platforms, tanks, stairs and other places inside the plant that present the risk of

falling shall be fixed with the protective barriers and hazard warning signs. All the parts of exposed

power driven production facilities will have protection guards fixed on them.


The fires of non-ferrous mines are primarily caused by open fire activities of welding and electric

equipment or lines. With the increase of automation, the risks of fires caused by electricity are

also expected to increase. The following protection measures will be put in place:

The selection of electro-mechanical equipment will strictly conform to the electric fire-protection

standards. These will have grounding connection fixed on them and other facilities to prevent

electric leakage and overload.

All places which may generate fire, such as the fuel or organic tanks, extraction plant and so on,

will be equipped with fire fighting facilities, mainly the foam type fire-extinguishers. There will be

special C02 (black mark) and dry chemical (blue mark) extinguishers near the electro-mechanical

devices, and the fire fighting water pump connectors on the fire fighting pipelines.

Welding work will be carried out in non-inflammable areas. These will be screened with steel

panels and equipped with suitable fire fighting facilities.

Fire and explosion protection of the oil tanks

There will be permanent fire-protection thunder-proof facilities for oil tanks. The tanks will be

made of non-combustible materials and safety and hazard symbolic signs will be placed around

them. The tanks will be fixed with fire ladders and foam fire extinguishers will be posted around


2.3 Ventilation

Measures to prevent dust and harmful gases

The closed hood systems will be installed at the transfer points of the conveyors and feeders to

extract the dust generated in the Crusher Section as well as at the Agitation Leach Plant. Other

housekeeping measures to ventilate and refresh air will be employed in order to maintain the

quality of the working environment and meet national industrial hygiene standards.

Measures to eliminate noise

Because of the high noise levels generated from the Crusher Section facilities, measures to

minimize noise will put in place. Facilities of international advanced levels to reduce vibration and

minimize noise will be installed.

All the air-blowers will be fixed with silencers, and high-vibration facilities will be fixed with the

damping devices. Places like control rooms will be soundproofed.
