TINOFAMBA NEVANOFAMBA KUWADZANA 1 STUDY CLUB 1 MINING AND PROCESSING OF MINERALS - Mining is the extraction of rocks or mineral resources from the ground. - There are 3 main methods of mining: - Open cast / open pit / surface mining - Underground / shaft mining - Adit / drift mining 1. Open Cast / Open Pit / Surface Mining - Is a method of extracting rocks or minerals from the earth by their removal from an open pit. - It is used to extract mineral resources that are situated less than 50 meters from the ground surface. - The overburden is removed using large excavators and draglines. - It is the method used to extract coal at Hwange and even asbestos in Zvishavane. Advantages of Open-cast / surface mining - Open-cast mining is generally less expensive than underground mining. - It is considered safer than underground mining as it eliminates the risk of tunnel collapses and gas explosions. - Allows for more efficient extraction of minerals, with better recovery rates.
