Oct 03, 2018· Oct 03, 2018· In March 2018 there were a little more than 328,000 people employed in support activities for mining, up from 278,000 in March 2017, and down from a high of about 458,000 in December 2014. Employees in private mining, quarrying, and oil and gas extraction industries earned, on average, $103,000 in 2016 and $102,000 in 2017.
Similarly, when the wages of the miners are compared to the estimated cost of living for the copper belt (i.e. main mining region in Zambia) of US$390.29), it can be seen that while the wage of the highest paid employee is still about 2 times above this regional living wage estimate, that of the lowest paid employee is about 25 percent less ...
copper mining industry has virtually disappeared within the last 40 years due to the effects of depletion and the rising cost of labour- intensive mining from rich but deep and inaccessible ores. The decline in average grade appears together with a decrease in the variance of the grade of ore mined.

demand for mining products. It's not all about China Infrastructure-driven growth in Asia, mainly China, has resulted in above-average economic growth and a significant increase in demand for commodities like iron ore, copper and coal. However, as can be seen from Figure 2, the USA and Europe account for more than 40 per cent of global GDP.

Mine cost estimation may be done at many levels. At first it may be a simple "back of the envelope" estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them. In the final stages a detailed bottom-up estimation based on first ...

labor costs, these structural market trends put greater pressure on existing staff to do more with less, reducing employee productivity. • Declining resource quality. Between 2001 and 2012, the weighted average head grade for copper fell by almost 30% and nickel dropped by 40%. Zinc and gold grades each fell by roughly 10%.
