Once the pipes are found and the presence of diamonds is proven true and profitable, shanks are inserted into the ground at the ore-bearing pipes and huge amounts of soil are extracted. In order to make mining efficient and effective, the raw rock and soil are typically not examined on-site.
There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting.

You are asking a complicated question that combines strip ratio (waste rock mined per ore rock mined), grade (carats per tonne) and distribution (how many diamonds of a given size recovered). You need to know your strip ratio, grade and distribution to answer this question.
Kimberlite ore and waste rock are brought from the underground workings to the surface by haulage trucks using three portal entrances, and the material is dumped in a designated location on-site. Larger trucks haul the ore to the processing plant, and any waste rock goes to a separate dump location (figures 16 and 17).
