Rich ores amount to nothing without a perfect ore dressing process, even if the grade is higher
1. It is the most important factor to determine mineral processing technology and investment cost budget, then avoid detours during the investment and reduce development risk.
2. It is the main technical index of the mineral processing plant. Even in the same mine, the oxidation degree of minerals is various, causing distinct processing conditions. So, customizing the most suitable ore dressing process is very important.
3. It is the primary basis of determining the rationalization of the plant, which helps you find the best balance among cost, index and economic benefit, reduce investment and production cost, obtain the maximum economic benefit.
4. It is the most direct scientific evidence of existing mineral processing plant upgrading, which solves many problems in original plant, such as low ore grade and recovery rate, high production cost, unreasonable equipment selection.
Every penny you spend on mineral dressing test will turn into the cost of earning
For example, a 1000tpd copper mine, 300 days of production per year, copper grade of raw ore (α) is 40 %, iron grade of concentrate (β) is 80 %. If the concentrate price is 4000 yuan/ton. When recovery rate rise 1% by mineral dressing test, economic benefits rise as follows:
- (1) Increase of concentrate yield :△γ=α（ε2-ε1）/β= 40%×1%/85% = 0.47%
- (2) Increase of annual income : 1000tpd * 300 days/year * 0.47% x 4000 yuan/ton = 5640,000 yuan/year, i.e. 5.64 million per year.
That is, only needs a mineral dressing test to rise 1% recovery rate, the enterprise can earn 5.64 million per year! What if the recovery rate is higher? Or is your ore worth more?
