Tantalum resources are widespread all over the world, with the most important known resources being found in Brazil and Australia. Large deposits are found and mining operations are prospected in Australia, Brazil, Canada, Mozambique and Ethiopia in 2008; witheconomic situation changes in the world,tantalum mining operations in 2009 are mainly processed in Brazil, Ethiopia and China, with additional quantities originating in central Africa, Russia and Southeast Asia.In 2010 production is resumed in Mozambique, followed by Australia in 2011 for a seven month period before stopping again, while Ethiopian production was stopped in 2012 due to transport difficulties. Brazil remains the major producer of tantalum raw materials.
Tantalum ore mining can be operated by open pit mining method or underground mining method according to ore deposit depth and properties.
Open-pit tantalum mining is a type of strip mining in whichthe tantalum ore deposit extends very deep in the ground,necessitating the removal of layer upon layer ofoverburden and ore.In many cases, logging of trees and clear-cuttingor burning of vegetation above the ore depositmay precede removal of the overburden. Theuse of heavy mining machinery, usually bulldozers anddump trucks, is the most common means ofremoving overburden.Mining operations consist of conventional surface mining activities such as drilling, blasting, loading, crushing, screening, separation and transportation etc.
In underground tantalum mining, a minimal amount ofoverburden is removed to gain access to the tantalum oredeposit. Access to this ore deposit is gained bytunnels or shafts. Tunnels or shafts lead to a morehorizontal network of underground tunnels thatdirectly access the ore. In an underground miningmethod called ‘stopping’ or ‘block caving,’ sectionsor blocks of rock are removed in vertical stripsthat leave a connected underground cavity that isusually filled with cemented aggregate and wasterock.
Although tantalum ores contain elevated levels ofmetals, they generate large quantities of waste.For example, the tantalum content of a goodgrade tantalum ore may be only one quarter ofone percent. Therefore, after extracted, the next step in tantalum mining iscrushing and grinding the ore and separating therelatively small quantities of metal from the nonmetallicmaterial of the ore in beneficiationoperation.
Crushing is first processing operation and integral in tantalum mining plant.Tantalum crushing produces very fine particles thatallow better extraction of the tantalum metal. In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.Tantalum crushing can be operated in three stages according to production requirements, including primary crushing, secondary crushing and tertiary crushing. SBM customize tantalum crushing solution and provides complete range of crushing plant for tantalum ore mining operation.
Tantalum crushing process prepares the ore for further size reduction or for feeding directly tothe classificationor concentration separation stages.The tantalum crusher machine is available with jaw crusher, impact crusher, cone crusher, gyratory crusher, and mobile crusher etc.
