The primary sector of the economy includes any industry involved in the extraction and collection of natural resources; such as farming, forestry, mining and fishing. The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries.
Let us first understand the differences between the different sectors of the economy, so that it will be easier for us to understand the factors responsible for the location of primary, secondary, and tertiary sector industries in various parts of the world (including India). Primary activities

Each step represents the distance away from the natural environment; primary industries extract natural resources while secondary industries turn those resources into products. Examples of primary sectors of industry including agriculture, mining, oil exploration, forestry, farming, fishing and hunting.
The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher
The net effect of these supergene processes is to move metal ions from the leached zone to the enriched zone, increasing the concentration there to levels higher than in the unmodified primary zone, possibly producing a deposit worth mining. Primary zone. The primary zone contains unaltered primary minerals. Mineral alterations
Nov 21, 2018 The primary, secondary and tertiary sectors represent various business types and the goods they produce and sell. It's easiest to think of them as a chain of production, from extracting the raw materials (primary) through manufacturing (secondary)
It could, if necessary, be installed near the scene of mining operations, and would be set to deliver a 6- or 8-in. product, which could be conveniently transported to the crushing section of the flotation plant where it would be fed through the coarse ore bin to the primary breaker in the ordinary way.
The mining method determines the type and placement of primary development opening. E.g., in caving methods the openings may need to be placed outside the fracture boundary. If the integrity of the ground overlaying the active mining area can be ensured primary openings can be located centrally b) Production rate and Mine Life
Primary and Secondary DDC-Sizers feature a unique hydraulic product size adjustment, which allows producers versatility if the product size requirements change. This feature allows producers not only the option of maintaining original size specifications, but also gives them the ability to adjust to meet changes in product size requirements.
Definition: A primary economic activity is a type of operation or industry that involves extracting or refining natural resources, such as mining, agriculture, forestry, and fishing.These economic functions deliver the raw material for other industries, which further refine and develop these materials into products to sell to customers.

The primary metal manufacturing subsector is part of the manufacturing sector. Industries in the Primary Metal Manufacturing subsector smelt and/or refine ferrous and nonferrous metals from ore, pig or scrap, using electrometallurgical and other process metallurgical techniques. Establishments in
Primary high explosives are extremely sensitive to mechanical shock, friction, and heat, to which they will respond by burning rapidly or detonating. Secondary high explosives, also called base explosives, are relatively insensitive to shock, friction, and heat.
(a) Those occupations which are closely related to mans natural environment. Hunting, fishing, lumbering, animal rearing, farming and mining are important example of primary activity. (b) This sector is also called agricultural and related sector. (c) Primary products are the base for all other products that we subsequently make. II. Secondary
The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, soft-rock, placers). The mineralogy of a gem dictates the type of geological environment in which it can be found.

The extraction of petroleum is the process by which usable petroleum is drawn out from beneath the earth's surface location. Locating the oil field On average, the recovery factor after primary and secondary oil recovery operations is between 35 and 45%. Enhanced recovery
Secondary industry Secondary industries are those that take the raw materials produced by the primary sector and process them into manufactured goods and products. Examples of secondary industries include heavy manufacturing, light manufacturing, food processing, oil
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

But for firms searching for rough stones, diamonds are divided into two types of deposits: primary and secondary. Once diamonds are formed under intense pressure deep underground, they are carried to the surface or at least relatively close to it by kimberlites. The diamonds found within these ore aggregates are called primary deposits.
