    Grinding Rule of Thumb Here is a list of Rules of Thumb often used in Grinding Circuits: Fine ore bins (or stockpiles) that provide feed to the grinding circuit should have a capacity equal to 30 hours of processingThe general rule of thumb is that the value of a mineral deed is about two to three times larger than the value of a mineral lease So, if the current going rate for leasing minerals in an area is $1,000/acre (say, with a 15% royalty rate), then the value for outright selling those mineral rights should be between $2,000/acre and $3,000/acreRules of Thumb for Valuing Minerals, and Why You ShouldFroth Flotation Rule of Thumb Here is a list of Rules of Thumb often used in Froth Flotation: Clean metallic gold particles (free gold) finer than 200 microns (65 mesh) float readily with appropriate reagents Gravity separation is desirable for larger particles Source: Mining Chemicals Handbook (Cyanamid)Froth Flotation Rule of Thumb
