One of the most troubling aspects of Wittenoom s story is the environmental contamination left behind by asbestos mining More than 3 million tons of asbestos tailings—the waste material generated by the mining process—remain scattered across the Wittenoom Gorge and surrounding areas

Objectives Asbestos is associated with South African diamond mines due to the nature of kimberlite and the location of the diamond mines in relation to asbestos deposits Very little is known about the health risks in the diamond mining industry The objective of this study was to explore the possibility of asbestos exposure during the process of diamond mining
Commercial asbestos mining started in 1954 and ended in 1985 Commercial nephrite mining began in 1971 peaked in 1975 and ended in 1981 We recommend that people should 1 only visit the mine on rainy days 2 do not process fibrous ores collected near asbestos mines and 3 do not process fibrous ores collected from asbestos mines
Ore processing techniques such as milling and crushing further enhance the mineral reactive surface area to promote passive carbonation [4 5 6] The global CO 2 sequestration potential of the ultramafic mine tailings asbestos talc etc is estimated to be about 175 Mt CO 2 /y
FIGURE 1 Asbestos Mine situated within a mountainous forested area 2 EARTHWORKS Waste tips The asbestos mine pit is bound by Livadhi valley in the North and the Loumata valley in the South and the two valleys meet about 700 800 m downstream of the mine pit Mining operations in the early part of the 20th century were of a small scale
The harmful effects of some minerals are mostly evident from its site of occurrence process of mining post mining wastes left over and even in finished products The current review focuses to evaluate the hazardous nature of minerals cautions associated with its mining drastic effects on human health and ecosystem as an eye opener to us
South African asbestos mining officially ended in 2008 Regulations passed in March of that year prohibited the use manufacture and processing of asbestos in the country Before that South Africa was a major producer of asbestos products including insulation pipe linings fire blankets and brake pads and linings
In the 65 years of Zhetikara chrysotile asbestos deposit exploitation based in the city of Zhetikara Kostanay region the local processing plant processed about 310 million tons of asbestos ores
Asbestos is widely used in construction manufacturing and other common industrial fields Human activities such as mining processing and transportation can release heavy metals from asbestos
The closure of the Wittenoom asbestos mine was for economic reasons such as transportation and labour costs rather than for controlling the occurrence of dust diseases Many workers were exposed to asbestos through the process of exporting crocidolite and chrysotile to other countries From the late 1960s there was a decline in
The paper [14] examines the results of studies on the comprehensive processing of waste concentration tailings of chrysotile asbestos technology based on physical methods granulometric separation gravitational separation electromagnetic separation vibrational separation makes it possible to obtain olivine forsterite spinel pyroxene chromite

supplies and input of the current process In other cases the open pit mining process is analyzed by changing its technologies in the mining process and assuming that this change reduces the inlet ore to 60% by discarding 40% of material without gold and by reducing supply consumption by 25% By improving the system efficiency the exergy
The mining process is responsible for massive waste displacement to the environment in different ways Fine particles with high airborne transport and floating capacity for example have a high capacity to contaminate the air of the mining region in addition to being able to be disseminated through the air over large distances creating a vast spectrum of
Asbestos Mining Exposure Long exposure to asbestos while mining caused many miners to develop long term health complications later in life specifically The first recognition of these negative health implications were discovered in 1899 by Dr Montague Murray but protective legislation was not introduced until 1971 leaving miners to
