Based on a large amount of data, this paper summarizes the role and control of lime in flotation, cyanidation, amalgamation and other operations in gold mines based on the system of years of production experience. Due to the limited level, there are inevitably many shortcomings, and many criticisms and exchanges are expected. Its purpose is to inspire and attract experience.
Generally the driven mill sheave is of split hub construction to facilitate field assembly. V-belt drives allow use of higher speed motors, generally low in initial cost. Motor speeds should be between 580 and 1160 rpm. The lower speeds apply to large diameter mills, the higher speeds to the smaller. DIRECT CONNECTED Ball Mill DRIVE.

This is another article in my series on the smelting of metals, this one focusing on the smelting of copper. We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process.
During the rapid development of the economy, the progress of metallurgical industry and its science and technology, and the continuous mining of iron ore resources, high - quality iron ore resources are declining in the industry. Facing mankind’s ever-increasing demands on the living environment, “Environmental Protection Act” is promulgated and iron ore mining gradually disappear. To protect the environment, relevant industries are developing and testing, and finally, the production technology of iron powder is adopted to “make” the iron powder resources.
Large numbers of iron ore mines are in operation in Orissa, India to meet theinternal and export demand of iron ore for iron and steel making. During the process of mining relatively lower grade iron ore containing 56-58% Fe is also being generated and stockpiled separately due to less market and industrial value. The accumulation of these lower grade lumps and fines are increasing day by day due to increase in the regular production of iron ore for steel industries. Simple washing of these low grade ores by scrubbing could not upgrade the iron content as evidenced from some laboratory studies.
The most common used magnetic separators are high-gradient magnetic separation (HGMS), high-intensity magnetic separation (HIMS) and low-intensity magnetic separation (LIMS), etc.
Seven out of the top 10 biggest iron production centers are located in Western Australia, and with whopping 697Mt of iron ore produced in 2014. This Australian state is believed to be the biggest jurisdiction in the world in terms of iron ore output.
