Critical Mineral Resources of the United States - Cobalt

COURSE NO: P01-006
Critical Mineral Resources of the United States - Cobalt
Course Highlights

This online engineering PDH course provides information on the global distribution, availability, mining, production and the industrial use of the mineral resource, Cobalt, which is considered a critical mineral resource in the United States.


In the past several decades, many changes have taken place in the resource sector within the United States. These changes have been exacerbated by the increased use of certain elements critical to manufacturing and high technology. The mineral elements were listed as critical and (or) strategic in one or more of the recent studies based on assessed likelihood of supply interruption and the possible cost of such a disruption to the assessor.


Cobalt is considered to be a critical resource and currently less than 7% of the used amount of cobalt is mined in the United States. Additional cobalt is refined from scrap, but 76% of the cobalt used in the United States is imported. Cobalt is a silvery gray metal that has diverse uses based on certain key properties, including ferromagnetism, hardness and wear-resistance when alloyed with other metals, low thermal and electrical conductivity, high melting point, multiple valences, and production of intense blue colors when combined with silica. Annual global cobalt consumption was approximately 75,000 metric tons in 2011.


This 1 PDH online course is applicable to industrial, mining, chemical, and geological engineers that are involved with mining, processing, and industrial use of critical minerals and their chemical constituents.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Familiarizing with cobalt uses, demand, and availability of supply
  • Exploring strategic and critical resource issues related to Cobalt
  • Familiarizing with mineralogy, geochemistry and principal deposit type of Cobalt
  • Gaining a general overview on undiscovered and unconventional Cobalt resources
  • Learning about grade tonnage characteristics, mining methods, typical mine life and ore-processing methods
  • Understanding environmental considerations including human health concerns, ecological health concerns, sources and fate in the environment, mine waste characteristics and mine closure
Course Document
In this professional engineering CEU course, you need to review the course document titled, "Critical Mineral Resources of the United States - Cobalt”, which is based on the Chapter F of the document “Critical Mineral Resources of the United States—Economic and
Environmental Geology and Prospects for Future Supply”, dated 2017.
