Zorluk: KolayChemical Industries, Raw Materials, and Siting Factors

In the industrial production of cement in Nigeria, such as at the factory in Ewekoro, Ogun State, proximity to the bulk raw material is the primary factor influencing site selection. Which of the following is the principal raw material extracted at the site for this process?

  1. LimestoneCevap
  2. B
    Bauxite
  3. C
    Coal
  4. D
    Gypsum

Cevap

Limestone is the principal raw material for cement production and determines factory siting due to its bulk and heavy transport cost.
Limestone is the chief calcareous raw material needed in large quantities for burning in kilns to produce cement clinker. Because of its weight and bulk, cement factories are located directly at limestone quarry sites to minimize transportation costs.

Adım Adım Çözüm

1
Identify the industrial chemical process
The process described is cement manufacturing in Nigeria.
Establishing the main product helps determine the required starting materials.
2
Analyze raw material requirements for cement production
Limestone (CaCO3CaCO_3) forms the primary raw material component (calcareous material) used in massive volume.
Heavy industries sit close to raw materials when transport costs of heavy raw inputs outweigh other factors.
3
Evaluate Nigerian industrial geography context
Ewekoro in Ogun State and Nkalagu in Ebonyi State were selected for major cement plants specifically due to large natural limestone deposits.
This confirms limestone as the critical siting raw material.
