Zinc Mining and Processing: Everything you Need to KnowLooking back on the history of mining and up to presentday techniques, many advancements have occurred in the way mined materials are extracted. Heavyduty, durable and compact mining equipment has increased costeffectiveness and the efficiency with which we mine. As a result, the mining industry has been able to reduce waste, as well as dangerous chemicals.

Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today.

From coatings to compounds, zinc is used in many areas of our lives. Whether its used in the home or an industry setting, zinc remains an important material. Under the below topics, there are many more specific ways in which zinc is part of our work and our lives.

Although the largest zinc mine is the Red Dog Mine, located in Alaska, zinc mines exist in 50 countries around the world. Among these 50+ countries, the worlds largest zinc producers are Canada, Australia, China, Peru and the United States. A few zinc mines in Canada, Australia, Ireland and Namibia will close within this decade due to depletion. The major types of zinc ore deposits are generally found to be sedimenthosted, volcanichosted, intrusionrelated, Broken Ore type or Mississippi Valley Type.

The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earths surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once its removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized and contaminants are removed via filtration. In the foundry, the zinc goes on to take its final form.

Metals &Mining Sell Side HandbookMining Industry Overview

Mining is a primary industry which involves the extraction of ore (rock with an economic amount of mineral content) and coal. After the ore is mined, it is refined into metal for industrial and commercial use. For most global investment banking franchises, metals and mining is a subsector of a Basic Materials or Natural Resources (along with oil & gas) coverage group however, we have chosen to segregate M&M on this website reflecting minings prominence in Canadian industry and finance and

The Metals Cycle

The need for any metal is about supply and demand. Commodities are some of the most interesting real life manifestations of microeconomics (firms and when they begin and stop production). The main difference between factories and mines is that mines work with a finite resource, so when a mine runs out of copper, it must explore and develop a new mine (or expand the current mine) to continue its level of production. In an imaginary scenario, demand for copper is at an equilibrium, and will con

Mining Project Life Cycle

Economically viable mineral volume in a mine can be classified as the mines resources, and further broken down into measured, indicated and inferred resources. The three grades are differentiated through sampling. Sampling can be done through the components of a drill test or observing the composition of outcrops or other evidence. From the circumstantial evidence, geologists can give a reasonable estimate for how much of a desirable mineral is in the mine. After a feasibility study, the mea

What is the NI 43101?

Mining investors talk about the NI 43101all the time. It is the required format for any reporting for a mining company that discloses information on a Canadian securities exchange. Technical reports will be conducted by a geologist and outline assumptions for reserves and resources and other information relevant to a mining investor. The report is largely interchangeable with the JORC, which is the Australian standard.

There are two major differences between mining valuation and conventional valuation for runofthemill companies: 1) The discount rate2) Zero terminal value. These two are reflected in the DCF driven valuation metric for miners Net Asset Value or NAV. Mining companies do not use the Capital Asset Pricing Model that is common for most DCFs especially gold companies. Mining net present value will use a standard discount rate with a floor discount rate commonly used for the mined commodity plus a risk factor. Gold is the best example for why this is used in place of CAPM the yellow metal has a zero or negative beta due to its role as a safe haven asset. Gold and Platinum Group Metals (PGM) will have a floor discount rate of 5%, which will be adjusted upwards for political risk and stage of development (the difficulty of the geography is already baked into costs of extraction in the projected cash flows). Base or industrial metals (copper, tin and zinc) have the same rule exc

Total Cash Costs

Direct costs to extract an ounce of gold which are usually classified as operating expenses (mining and processing, but only cash expenses). All of these measures will fall as production ramps up as many fixed costs are spread out over the production and processing and mining benefit from economies of scale.

AllIn Sustaining Cash Costs

Sustaining capital expenditures are added to total cash costs as a more accurate measure of the cost of extraction as without the sustaining capex production would cease.

Mining credit is particularly interesting because of the cyclical nature of the business, the different supplydemand dynamics of different commodities and the unpredictability of cash flows. As was seen postfinancial crisis and the Chinese shift from manufacturing and construction to services (post 2014), mining has seen peaks and troughs where the peaks allow companies to access questionably cheap credit and the troughs result in financial distress, waivers, bankruptcies and consolidation. The death of coal has also presented itself as an interesting development in credit, as some of the largest names such as Peabody and Alpha Natural Resources have filed for Chapter 11 Bankruptcy (and many other notable coal pure play listed in the US) indicating that even the most conservative stress scenario may not be enough. Similar to other natural resource sectors such as oil and gas, mining company profitability movements will be an amplified version of the underlying commodity produced

It is removed in a checkerboard pattern to leave permanent, solid salt pillars for mine roof support. Usually 45 to 65 percent of the salt is removed. The room height may average 18 feet in a bedded deposit to 100 feet in a dome mine.
