It is mined to an average depth of 2,800m-3,400m below surface and is one of the world’s deepest and richest gold mines with grades at over 8g/t. It is one of three AngloGold projects in the West Witts area apart from Savuka and TauTona mines.
بیشترCompounds at Kimberley. An earlier form of compound developed in South Africa in response to copper mining in Namaqualand in the 1850s. However, the systems of control associated with labour compounds became more organized in the context of diamond mining at what became Kimberley from the early 1870s.. By 1872 more than 50 000 people had converged on the Diamond Fields.
بیشترIn 1885, 15 years after diamonds were first mined at Kimberley, mining companies began to introduce a system of closed compounding to house their black labour force. Essentially, closed compounds ...
بیشترThis section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of gold. For each compound, a formal oxidation number for gold is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an ...
بیشترDiamonds are found in the far north of Canada where it is usually always snowing and in cold places, such as the Northwest Territories Yukon and Whitehorse. Diamonds Are sometimes used to use as tips for drills because they are extremely hard so they can cut any other materiel on
بیشترFurther investigation revealed a number of platinum compounds were being formed due to reaction of the buffer and platinum electrode and subsequent characterization of these compounds isolated cisplatin. Cisplatin was found to inhibit cell division thus causing the elongation of the bacteria, and was tested in mice for anticancer properties.
