Mode of occurrence of minerals
- Minerals that occur in small quantities/ lodes/veins may limit exploitation
since they are of low commercial value unless the mineral is of high value they will be exploited / large deposits are extracted as they are likely to beprofitable / can sustain the mining process over a long time
-Minerals at or near the surface/alluvial deposits are easier/cheaper to extract
/ the deep seated minerals are expensive to extract.
Minerals close to the surface/beds/layers/seams are extracted using open
cast method of mining/minerals that occur deep in the ground/veins/lodes are extracted using underground / shaft method
Transport
Efficient transport links allow mineral products to be moved from the
mining site to the ports / markets without delay.
Minerals that are bulky require railway/water/ cheap transport system to
reduce the total cost of production.
Mineral deposits in remote areas/poorly developed transport system are less
likely to be exploited
Level of technology
Advanced technology has improved mining operations thus leading to high
quality / large quantity mineral products.
High level technology allows for effective exploration of minerals
leading to accurate location of minerals.
Advanced technology boost effectiveness in production hence reducing
wastage.
High level technology in mining operations reduces the destruction of the
environment /improves the health and safety of workers.
Low level technology limits exploitation/low quantity mined
