Agglomeration is closely related to, but distinct from, industry clusterswhich are familiar to many due in part to michael porter and others work on the u.s. cluster mapping project. in a nutshell, the forces of agglomeration contribute to the formation of industry clusters, but one should refrain from using the terms interchangeably.6
Agglomeration techniques are widely used by industry to form fine particles into larger masses that are easier to handle and process. one area where agglomeration is potentially useful is in heap leaching operations. without agglomeration, fine particles travel through the heap, clogging the spaces between the larger particles and resulting in poor leach.7

Impact of labour cost on location of an industry. according to webers least labour cost theory, if the labour cost is very cheap at a specific region then the industry would be shifted from the least transportation cost to least labour cost provided the saving in labour cost would be greater than any additional transport cost. the labour cost is the major factor for the development of the.

Similarly for cement binders, cement functions effectively as a binder in the actual agglomeration process, but as a fertilizer product, the pellets would not break down, and would likely leave cement particles in the soil. has been a leader in the agglomeration industry since the 1950s, helping customers solve material problems through.
