Natural Resources(PDF/744KB)
CHAPTER 7: NATURAL RESOURCES I. Introduction For many African countries the natural resource sectors (oil, gas and mining – the extractive industries) are important parts of the economy. If harnessed right, these natural resources can constitute a huge opportunity for development. By exploiting its natural resource base, in essence converting its underground minerals and agricultural potential into human and physical capital to create inclusive growth, Africa could by 2050 become factory and granary to the world, just as Britain and the US were the factories and the US and Argentina the granaries in the second half of the 19th Century, followed by China and Australia in the 20th Century. This is a vision of economic convergence for Africa’s resource-rich economies, where these countries “catch up” with other high and middle income countries to narrow the gap in per capita income and development outcomes. Over the next 40 years the African continent could build on its natural resource and agricultural production base to become an important supplier of intermediate and finished goods and agricultural products, relying on a diversified private sector and a high degree of economic and geographic integration. Africa’s factories and agribusiness processing centers, linked by world class regional infrastructure (rail, road, electricity and information and communication technology (ICT)) to its raw material production centers and farms, could transform these inputs into intermediate and finished products, from where they would be exported to clients on the continent and across the world. By 2050 Africa could also possess a significant service sector, particularly in natural resource extraction-related activities such as mining finance, technical design, and environmental and social analysis. -
The Bushveld Igneous Complex
The Bushveld Igneous Complex THE GEOLOGY OF SOUTH AFRICA’S PLATINUM RESOURCES By C. A. Cousins, MSC. Johannesburg Consolidated Investment Company Limited A vast composite body of plutonic and volcanic rock in the central part of the Transvaal, the Bushveld igneous complex includes the platinum reef worked by Rustenburg Platinum Mines Limited and constituting the world’s greatest reserve of the platinum metals. This article describes the geological and economic aspects of this unusually interesting formation. In South Africa platinum occurs chiefly in square miles. Two of these areas lie at the the Merensky Reef, which itself forms part of eastern and western ends of the Bushveld and the Bushveld igneous complex, an irregular form wide curved belts, trending parallel to oval area of some 15,000 square miles occupy- the sedimentary rocks which they overlie, and ing a roughly central position in the province dipping inwards towards the centre of the of the Transvaal.

The timing and mechanism of the rise of atmospheric pO2 level in the early Precambrian have been long debated but no consensus has been reached. The oxygenation of the atmosphere and oceans has significant impacts on the evolution of the biosphere and the geochemical cycles of redox-sensitive elements. In order to constrain the evolution of the atmosphere, oceans, biosphere, and geochemical cycles of elements, a systematic and multidisciplinary -

Email: [email protected] The Bushveld Complex in South Africa is the largest layered intrusion on Earth. Its upper part is known for huge resources of iron, tita- nium, vanadium and phosphorus. Associated with the layered character of the rocks, these resources are enriched at certain levels of the intrusion, which makes it important to understand the formation processes of those layers. In this paper we give an introduction and overview of recent debates and challenges. Key Words: layered intrusion, Bushveld, resources. INTRODUCTION Fe, Ti, V and P never or only rarely occur as native elements in nature. Minerals, rich in one or more of these Iron (Fe), titanium (Ti) and vanadium (V) are important elements are mined and their components are extracted. -
FISHING in the WORLD This Is the Exploitation of the Aquatic Animals from Water Bodies Like Lakes, Rivers, Ponds, Seas, Oceans for Commercial and Subsistence Purposes
FISHING IN THE WORLD This is the exploitation of the aquatic animals from water bodies like lakes, rivers, ponds, seas, oceans for commercial and subsistence purposes. It is common in countries like Canada, Norway, Japan, S. Africa, Morocco, Namibia, Angola, Nigeria, Finland, Sweden, Chile. Types of fishing There are two types of fishing: Marine fishing takes place in oceans, seas and it is most important for commercial purposes and for large scale. It helps in exploitation of marine species like Tuna, Cod, Mackerel, Heming, Sardines, Haddock, Anchories, Crabs, Halibut, Oysters, Yellow star fish, Whales, Sharks, Bonito. Takes place in pacific, Atlantic ocean, North sea, Indian (takes place in salt water). Fresh water fishing: this takes place in fresh water bodies found in the interior or inland like in lakes, rivers, swampy areas, streams, ponds. Fresh water species like Tilapia, mud fish, Nile perch, Silver fish, lung. This is common in the tropics equatorial regions, low developed countries like the Congo and Amazon basin. It is less developed and it contributes to small percentage. Methods of fishing: 1. Drifting: This is the use of drift nets which are hanged vertically in the sea like tennis with open end where the fish enters. It has floaters on top and sinkers at the bottom which help it in balancing. It is tied with a rope and pulled by a boat. It has locks for opening and closing. It is mostly used for getting pelagic fish which live near the surface of water like sardines, herrings mackerel. 2. Trawling: This is the use of trawl nets shaped like a bag with open end where the fish enters. -

Mining & Mineral Beneficiation
ZAMBIA DEVELOPMENT AGENCY Sub-Sector Profile: Mineral Beneficiation Industrial Minerals ZAMBIA: “Africa’s New Frontier for Investments and Profits” June 2013 I. OVERVIEW Located at the centre of southern central Africa, Zambia is a politically stable country with a growing economy; it is in the midst of transforming itself into an economic hub for the rapidly growing central and southern African regions. In Zambia, the sector is the backbone of its economy, contributing 9-10% of GDP. From 2001 to 2009, the mining sector annually grew by 9% and is forecasted to grow from US 590 million in 2000 to US $ 17 billion by the year 2017. Zambia possesses one of the world’s most vital and complex metallotects and is internationally recognized as having a good mineral potential. Copper is the main mineral resource, accounting for roughly 75% of the country’s total export earnings. In Zambia, refined copper is its major export product. The export value of refined copper and copper alloys (unwrought) alone accounts for 63.5 % of its entire trade value. The Zambian Government has been encouraging domestic value-addition of mineral resources by providing generous incentives. Through these efforts, Zambia has established itself as the top producer and exporter of refined copper in Africa. In addition to copper, there is also a broad spectrum of mineral resources available for further exploration, mining and beneficiation. Additional investment opportunities are especially present in mining and beneficiation of metallic minerals, such as iron, manganese, and uranium, and fuel minerals such as coal. Driven by increased consumption in emerging Asian economies, demands for Zambia’s mineral resources are expected to grow further. -
