Calculate Iron Ore Resources

Iron Ore lateritic , in general were exposed as a sandy to boulder iron on the surface, and dominantly hosted on the volcanic tuff or and sediment material as product of volcanic.

Laterite characterist as redish to brownish color, with in sand , pebble, couble to big boulder size on the surface and in view meter depth depend on the intensity of lateritisation to the host rock.

To calculate geological resources so far you need to assumed some of term parameter as follow:

Assumed a long distance of laterite , feet, find out the limit by trenching

Assumed width of laterite, feet , find out the limit of exposed by trenching.

Assumed thick of laterite , feet , by check on the wall of your tranching.

Observe and see the concretion factor to eliminate a boulder and coarser material of iron and to separate clay and others impuritism on the aggregate, say CF = 20% only or up to 50%. Mean that there is 50% clay and 50% fragment, can be pebble or boulder.

So that you have a Volume = distance x width x thick x CF

To calculate tonage used your number of loose density in between 1.3 up to 1.6 persizely.

In according to your data observation , also consider to the confidence of geology , sure or not sure base on the exposure and interpretation.

In generally the iron ore were on the low grade material, so that you need to increase grade by select by washing material, and will decreasing tonage, but increasing grade. It is ok.

To calculate more final result after washed a material iron ore to get the increasing grade

The factor of washed material will be calculate as grade content and concretion factor parameter.
