ELANDSFONTEIN

THE AREA


ELANDSFONTEIN FARM

Elandsfontein is an expanse of almost
5,000ha of agricultural land on the West Coast of South Africa. It contains the Elandsfontein phosphate deposit, the largest sedimentary phosphate deposit in South Africa.


SURROUNDING COMMUNITIES

Neighbouring local communities from the Saldanha Bay Municipality include Hopefield, Langebaan, Vredenburg and Saldanha.


LANGEBAAN LAGOON

The Langebaan Lagoon is 15km to the west
of the deposit. The protection and preservation of the lagoon is of the utmost importance and will be ensured before, during and after operations.

GROUNDWATER FLOW


ELANDSFONTEIN AQUIFER

An aquifer is a geological formation consisting of sandy sediments that hold water or allow water to move through it. At Elandsfontein, the aquifer lies approximately 20m below
the surface.


WATERSHED

A watershed exists approximately 10km to the east of the Elandsfontein area, which directs the water in the Elandsfontein aquifer in a south westerly direction towards the Langebaan Lagoon.

BEFORE OPERATIONS

AREA OF OPERATION


ELANDSFONTEIN DEPOSIT

Operations began with the exploration and development of the Elandsfontein sedimentary phosphate deposit. The operation will be limited to a fenced off area of 500ha. At any time, the open area of the mine excavation will be limited to 60ha.


ELANDSFONTEIN FARM

Elandsfontein is home to a thriving natural ecosystem comprised of Saldanha Flats Strandveld, Langebaan Dune Strandveld
and a growing wildlife population including eland, kudu, gemsbok, duiker, ostrich, zebra and bontebok.


ELANDSFONTEIN FOSSIL AREA

The dune fields, 5km to the east of
the deposit, have been declared a
Provincial Heritage Site by the Western
Cape Government.

DURING OPERATIONS

AREA OF OPERATION


PIT AND PLANT

The 500ha operations area will contain the excavation area, the plant and the office.


SOFTS STOCKPILE

The overburden that is removed from the mining area for the early production period, will be deposited on the softs stockpile.


INFRASTRUCTURE

The operation will be accessed via a newly developed mine access road running 13km south from the R45. New power lines have been erected to connect the operation to the Eskom grid. Water lines will be laid to connect the operation to the district municipality’s water supply.

THE PLANT


FLOTATION COLUMNS

Silica sand and phosphate are separated by floating the silica sand in water which leaves behind the phosphate.

 

CONCENTRATE STORAGE

Final concentrate is stored in a closed shed.


WATER STORAGE

Water on site is stored in lined water dams.


EMPLOYMENT, UP-SKILLING AND CARE

Up to 1,100 people have been employed during the construction phase of the project with nearly 50% local employment. Over 450 people will be employed as members of the Elandsfontein operational workforce.

 

OFFICE

The mine offices and access road will be left behind after mine closure, to serve as a tourist centre, allowing access to the fossil area and Elandsfontein Nature Reserve.

THE EXCAVATION AREA

A carefully considered mining process has been designed to allow for rehabilitation of the land while mining is in progress. Rehabilitation will begin 25 months after the first soil has been turned.

This method ensures that there is reduced impact on the visual landscape over the course of the project and that the vegetation that
is disturbed will be re-established as quickly
as possible.


Before mining begins a search and rescue for any protected plant species is conducted. Any plants recovered are removed to a nearby nursery for further propagation.


The mine is excavated in 50m wide strips.


As soon as a strip is completed, overburden removed from the new strip is placed back
into a previously mined strip, including the careful replacement of the vegetative top layer of soil. This process allows the land to recover during operations over the course of the project, with seedlings establishing 5 months after placement.

PROTECTING THE AQUIFER
AND THE LAGOON

Kropz is working to eliminate any negative impacts from the operation on groundwater quality and availability by developing a number of groundwater monitoring programmes that will ensure the protection and preservation of the Langebaan Lagoon.

A borehole dewatering and recharge system will ensure that the fresh ground water flowing towards the lagoon will be not be affected in any way.


Water is pumped up from underground
before it reaches the deposit. This ensures that the mining area remains dry and the water does not come into contact with any mining activities.


The water is transported above ground via a closed dedicated pipeline to boreholes beyond the deposit, ensuring the water chemistry remains unchanged.


Water is pumped back into the ground to restore the water table to its natural level, with no impact on the quality or the quantity of the groundwater flowing into the Langebaan Lagoon.

RELATIVE VOLUMES OF
THE MINING PROCESS


Overburden (sand) and ore is removed to a depth of 70m below natural ground level.


The overburden that is removed from the mining area for the early production period, will be deposited on the softs stockpile.


The ore is processed to recover the phosphate. The phosphate rock concentrate, at a grade of 32% P2O5, accounts for approximately 25% of the plant feed.


The remaining sand, having naturally expanded in the process, will be returned to fill the excavation pit.

AFTER OPERATIONS

ENVIRONMENTAL
REHABILITATION

Kropz has partnered with leading environmental consultants to improve our understanding of possible environmental impacts of the project, and how to mitigate them appropriately, using the best
available science.


ELANDSFONTEIN NATURE RESERVE

Kropz will convert more than 10,000ha agricultural land in the area (half of which has already been committed) into a major private nature reserve for the conservation of wildlife and local tourism.


REHABILITATED OPERATION AREA

Upon completion, as a result of the integrated rehabilitation mining process, the project area will be returned to a functional ecological state that can be incorporated as part of the Nature Reserve.


PALEO RESEARCH AND TOURISM

Kropz, in collaboration with Heritage Western Cape have declared the Elandsfontein Dune Fields a Provincial Heritage site. Long term planning includes the establishment of educational, employment and commercial opportunities for local communities.

OUR LEGACY


ELANDSFONTEIN NATURE RESERVE
AND ELANDSFONTEIN DUNE FIELD
Kropz partners with leading environmental experts and consultants to improve its understanding of possible environmental impacts on its projects, and how to mitigate them appropriately, using the best available science.

As a part of an offset programme being finalised for the Elandsfontein project, Kropz will facilitate the establishment of the Elandsfontein Nature Reserve. Such conservation areas may become part of a formally protected environment, proclaimed in terms of legislation.
