parameters for ore mineral evaluation

Evaluation of Mineral Deposits Earth Science

The estimated grade and quantity of ore in the ground is usually referred to as the geological reserve. But, since the total amount of ore present can be quite different from that which is extractable at a profit, a mining reserve is calculated which allows for economic conditions, limitations of the mining method and dilution of the mineral by

The method selected and the parameters assumed will determine the cost and rate of mining, as well as how much of the ore reserve will eventually be recovered. The questions below assume that the mine is operated by the owner, although the data requested will also be needed if the operation is contract mined.

METHODS OF ORE RESERVE ESTIMATION_EXAMPLE Basic

Aug 18, 2019· Value and extent of a mineral deposit can be estimated using classical methods or geostatistical methods. The simple yet accurate ore reserve estimation technique used is classical methods. Classical methods employ simple geometric function and rules that are easily applied to simple uncomplicated orebodies.

Evaluation of Physico-Chemical Parameters and Minerals

Physico-chemical properties and minerals status is an important decisive factor for assessment of drinking water quality. There are limited literatures on this aspect for drinking water quality of high altitude areas; therefore, the present investigation was carried out to evaluate different physico-chemical parameters and some essential minerals status in different drinking water sources.
