Jun 09 2014 In 2016 the price for large graphite flakes is expected to reach 996 U.S. dollars per metric ton. Until 2020 the price for this flake grade was expected to increase to 1165 dollars per metric.
Once corrected for inflation at the Australian CPI the increases are more like 3.50t per year for the small mines and 1.40t per year for the large mines expressed in 2016 dollars. Thus we can say that underground mining costs in Australia have increased significantly faster than the inflation rate despite improvements in technology.
May 14 2019 As the graphite will be shipped in 26 tonne containers a 17000 tonne per year production scenario would need just over 650 containers. A 50000 tonne per year operation would need to secure cargo space for 2000 containers which could qualify for bulk pricing when negotiating with the shipping companies.
For example the costs of purifying a 95 per cent grade graphite to a minimum battery grade of 99.95 per cent is approximately 3000 to 5000 per tonne. The cost of purifying Lac Knifes 98.3 per cent grade to battery grade quality is estimated to be between 500 and 1000 per tonne. Graphite sources

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.
graphite. As noted Sri Lankan vein graphite sells at around USD2300 per tonne in its raw form. Even if the upgrading to battery-grade graphite costs US100 per tonne and that is a far cry from reality with the selling price of the upgraded material in the US5000 per tonne range the economics are very favourable for Ceylon Graphite.

Mining - Unit Costs The cost per ton for the month of December was 0.81 per ton reflecting the short haul distance to the crusher. For 1999 and beyond mining cost per ton is expected to be in the range of 0.85 to 0.90. The depth of the pit and the height of the heap leach pad impact the truck-haul cycle time and unit cost which is the most .
generate cost savings of between 1.50-2.00 per tonne. ie a return of 9 – 12 million per annum per machine. Best practice may not be possible on all sites but apply this benefit to a substantial portion of a miners fleet and the financial upside quickly mounts. • Benchmarking of
