World mineral loss and possibility to increase ore recovery …

3.2.2. Ore recovery from mineral processing. It is difficult to find the data of ore recovery ratio in mineral processing from publications, so only a few recovery data were collected, as shown in Table 2. It can be found that the mean ore recovery ratio from the production of mineral processing is 80.9%, and that from research experiments is ...

What is a theoretical grade-recovery curve? An example.

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify …

Lecture 08 Mass Balancing

The Paragominas processing plant mass recovery was around 65%. But when calculating the mass recovery from reconciled mass values, the recovery was closer to 60%. This value indicates that 35% of the input mass to the plant is lost as reject (tailings), when the suitable value from the project should be around 30%.

Mineral processing calculation

The mass of the recovered mineral can be calculated using the formula MR = MP * R / 100, where MP is the mass of the mineral in the ore and R is the recovery rate of the mineral. Related Questions.

If we consider the total Plant Feed of 2800 TPD as of the mass and we produce say 59% Cu Recovery or 84 TPD of Cu conc, we would find that 3% of the "mass" is in the concentrate. We therefore label %Mass Pull as the % of the material (mass) sent to flotation a "pulled/floated" into the concentrate.
