The Color of Responsibility: Ethical ...
ABSTRACT. The mining and processing of colored stones, a multibillion-dollar industry, spans 47 countries on six continents. Despite the industry''s high profile, an ethical, sustainable mine-to-market supply chain for these materials has still not been achieved, impacting the physical environment and quality of life for laborers.
Quartz Stone Manufacturing Process: Everything You Need to ...
· The manufacturing process involves a mixture of quartz aggregated chips pigments, additives, and resin binders. Engineered quartz stone for slab and countertop applications come in a wide array of colors, textures, and patterns. Depending on the manufacturing process, the texture can be either coarse or fine.
MINING. The first step in our mining process is to strip overburden (which is the rock and soil overlying a resource) away from the resource. We use multiple types of equipment to do this, such as scrapers, excavators, and haul trucks, depending on the digging conditions.

preference. Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage.

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Gemstone Mining Methods
· In all the mining methods the rocks are broken into medium or small chunks using the explosives such as dynamite. The broken rocks are then sent to the other processing plant where the gemstones are obtained in the form of raw stone. These raw stone reach to the next level of gemstone processing that involves cleaning, cutting and polishing etc.
Gemstone Mining Techniques — Gemstones and Sustainable ...
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.
