If you want to skip ahead and just enter your numbers, download the Free NRI Calculation Worksheet HERE. Net Revenue Interest = Net Mineral Acres / Drilling Spacing Unit Acres * Royalty Rate. Continuing our example, here's what we know: Net Mineral Acres = 16 Acres. DSU Size = 1280 Acres.

The weight of the crude ore can be measured by using belt weigher or other weighing equipment. But it is difficult to directly measure the weight of concentrate. A mineral processing plant usually determines crude ore grade, concentrate grade, and tailings grade through sampling and testing, and such data is used to calculate the …

The mineral processing sector holds a significant and growing share of the energy balance of the mining industry. Tromans [] reported striking data from the U.S. Department of Energy showing that 39% of the energy footprint of mining operations originated from beneficiation and processing operations in 2004.More recently, the …

Improved process production/recovery and quality/grade. Reduce process variability. Economic optimization. A small 1% process improvement in a $100M/yr. (small plant) production plant is $1M/yr. OSA system and installation is paid for in one year. Think about $500M/yr. or more.

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to 100% of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

The mineral is usually transferred to the froth leaving behind the gangue in the pulp. This is termed as direct flotation. However, during reverse flotation the gangue is separated into the float fraction while the valuable mineral is retained in the pulp. The process can only be applied to relatively fine particles.

This lecture overviews estimating methods for Mineral Processing capital and operating costs along with common aspects of financial analysis.
