The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath. When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of foam

Given the comparative advantage in mineral resources Zimbabwe has, in comparison with other Southern African countries and other developed coun-tries, it is therefore imperative to study the role these mineral resources play on the overall performance of the
resources, and (b) within the mineral sector, countries compete with one another for investment. Mineral exploration and development are the first stage in the process of mineral supply. The stages of mineral supply are: - Mineral exploration and development, in which mineral deposits are identified, evaluated, and prepared for mining.
The market economy gave newcomers advanced weapons and more resources. The traditional economies couldn't compete. The United States had many aspects of a traditional economy before the Great Depression. At the beginning of the 20th century, more than half of Americans lived in farming communities. Agriculture employed at least 41% of the
in mineral resources. There is not a great deal written on this topic, and so my review is necessarily broad rather than deep. In some cases I am only able to cite related and even tangential literature. I first define what is meant by trade in mineral resources. I then discuss patterns of trade in mineral resources.

The family diets to which some infants are weaned are also low in nutritional value. Indeed, many investigators [23,25,29] have reported that these traditional foods are low in protein and that other nutrients are lost due to poor processing. Bulk is a major problem of the traditional West African weaning foods [8, 20, 30].
