Organic Material Such As Ore

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...

How plastics are made :: PlasticsEurope

Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

What is Organic Waste? | DoItYourself.com

Organic waste is material that is biodegradable and comes from either a plant or an animal. Organic waste is usually broken down by other organisms over time and may also be referred to as wet waste. Most of the time, it is made up of vegetable and fruit debris, paper, bones, and human waste which quickly disintegrates.

The importance of soil organic matter

Soil organic matter is any material produced originally by living organisms (plant or animal) that is returned to the soil and goes through the decomposition process (Plate 1). At any given time, it consists of a range of materials from the intact original tissues of plants and animals to the substantially decomposed mixture of materials known as humus (Figure 1).
