Course objectives

Through a program of exercises, students gain practical knowledge needed to master the laboratory techniques for chemical analysis of seawater, as well as practical knowledge of the methods of exploitation of mineral raw materals from seawater.

Course enrolment requirements and entry competences required for the course

Enrolled in or passed the course Mineral Raw Materials from Seawater

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, students are expected to:
- carry out the analysis of seawater for the content of calcium and magnesium independently according to work instructions
- carry out the analysis of seawater for the boron content independently according to work instructions
- determine the CO2 content in seawater independently according to work instructions
- describe technological processes of recovery of magnesium oxide from seawater
- describe technological processes of extraction of common salt from seawater

Course content broken down in detail by weekly class schedule (syllabus)

During exercises, seawater is chemically analysed for the content of calcium, magnesium, boron and free CO2. Practical knowledge is obtained of technological processes of extracting mineral raw materials (magnesium oxide and sodium chloride) from seawater. List of Exercises:
Exercise 1. Analysis of seawater for its content of magnesium oxide and calcium oxide,
Exercise 2. Analysis of seawater for its content of CO2,
Exercise 3. Determination of boron in seawater,
Exercise 4. Recovery of magnesium oxide from seawater (seawater pretreatment, precipitation with 80% of the stoichiometric quantity of dolomite lime, washing and filtration, calcinations of magnesium hydroxide, chemical analysis of magnesium oxide from seawater),
Exercise 5. The visit to industrial plant – salt works - extraction of common salt from seawater.
