Detailed introduction

Metallic Deposits

The ore minerals in most of the world's iron and manganese reserves were chemically precipitated in the ocean and accumulated on the sea floor. Placer deposits are heavy metallic minerals, such as iron or titanium minerals, or native gold or diamonds, that have been concentrated by wave or water action in a river or beach environment.

Tackling Difficult Mixing Problems

Some of the most difficult mixing problems involve formulation (i.e., the combining of two or more ingredients) rather than complicated chemical reactions. If chemistry is involved, it is rarely more complicated than pH adjustment. In many cases, the simpler a process sounds, the more prob-lems that develop. In the case of formulation, those prob- Get price

What is Tungsten and Should I Buy It? – Jewelry Guide

Tungsten Shatters. Because tungsten carbide is so hard and brittle, it does not bend or lose shape. Instead, it can crack or shatter if dealt an extremely hard blow, much like a diamond. If your ring is exposed to rough wear and knocks, there is the likelihood that it will crack and come apart. Get price

Why Copper Tungsten?

May 07, 2013Tungsten, on the other hand, is brittle and its density makes it difficult to machine. High tool wear rates and long production times are inevitable.
