CRUSHING, SCREENING AND RECLAMATION
Ease of transport is only one of many exciting features on this
new model. The Warrior 600 screen is highly versatile with its
ground-breaking simple conversion from 3-Way Split mode to
Elaine Crewe, CEO of BAUMA
CONEXPO AFRICA says, “There are
some simple actions that can be
taken over the life of a mine, which
at the end of its production cycle, can have a
monumental impact in land rehabilitation.”
Kenmare Resources, an Irish company
with a Moma Titanium Mine in Mozambique,
for example initiated a simple yet effec-
tive waste management activity of growing
trees. Back in 2012, the company reported
that it had doubled the capacity of its
nursery, which had been constructed for the
rehabilitation of its mined areas. It increased
the type of plants being grown from six to
18 and twelve hectares of mined land were
rehabilitated and prepared for handing
back to the local government. In addition,
three trial plots were established on the
rehabilitation areas to determine the appro-
priate soil fertility enhancement strategies
to be used.
“Mines should have recycling projects
in play,” adds Crewe. “At this year’s BAUMA
CONEXPO AFRICA we will showcase waste
and water management by focusing on envi-
ronmental technology through hosting IFAT
Environmental Technology Forum Africa
– Water, Sewage, Refuse and Recycling –
Solutions for the Mining and Construction
Industry.” This forum, she says, will bring
together suppliers and consumers of innova-
tive solutions and technologies in the areas
of water, sewage, refuse and recycling.
Crewe emphasises that water manage-
ment is a critical focus area in Mining.
“Water is the ultimate enabler of living and
in Southern Africa we do not have high levels
of water security. Added to that, we depend
highly on shared fresh water resources, with
two or more member States sharing more
than 70% of these,” she says. “Mining and
Construction companies can play a proac-
tive part in addressing this risk.”
Patrick Hulley, managing director of Wilo
Pumps SA who will be exhibiting at IFAT Envi-
ronmental Technology Forum Africa says,
“It is absolutely crucial for companies to
manage the available water resources effec-
tively and to ensure that they participate in
a well-defined water management strategy.
Yet there is much room for improvement in
the definition and implementation of such
strategies, which are also a key factor in
Corporate Social Responsibility.” He points
out that some of the challenges within the
Water sector in SADC include the increased
demand for potable water, a lack of under-
standing surrounding the consequences of
not managing water resources effectively,
a further lack of maintenance practices and
a lag in new technology acceptance.
Wilo has researched and developed
numerous technologies that contribute to
effective water management strategies. For
example, an innovative Ceram Coating is a
method of coating parts of a pump, which
in turn reduces friction and raises pump
efficiency. He notes a waste management
example of a “highly efficient Solid Sepa-
ration system, which allows for the more
REPLANT, REUSE
and RECYCLE
Waste and water
management in the mining
sector may be considered
to be costly by many and
may be logistically and
technologically complex,
but it remains imperative for
mining houses.

BAUMA CONEXPO AFRICA
BAUMA CONEXPO AFRICA, Interna-
tional Trade Fair for Construction
Machinery, Building Material Machines,
Mining Machines and Construction
Vehicles takes place between 15 and
18 September 2015, at the Johannes-
burg Expo Centre (JEC). The premiere
of Bauma Africa in September 2013
attracted 754 exhibitors from 38 coun-
tries and 14 700 visitors from over 100
countries. Covering a total of 60 000
m2 of exhibition space (40 100 m2 net)
this is the biggest event for the sector
in Africa.

effective collection and transport of water
and waste water to treatment plants which
results in uptime of the operations to move
waste water from and around cities and
other areas.”
Crewe concludes: “Any negative environ-
mental and social impacts of a mine, both in
the short and long term, need to be miti-
gated against. As a resource rich continent,
those with mines in Africa have a respon-
sibility to protect, even nurture the local
people and land within their operations.
The good news is that there are technologies
available through which to do this.”
RECENT FAMILY ADDITION
