Tin - Wikipedia

Secondary, or scrap, tin is also an important source of the metal. Recovery of tin through secondary production, or recycling of scrap tin, is increasing rapidly. Whereas the United States has neither mined since 1993 nor smelted tin since 1989, it was the largest secondary

Fundamental study on tin recovery in acidic

The current recovery rate of tin metal is low and insufficient with just over 300,000 tonnes annually. The grade of tin concentrates in traditional smelting methods needs to be at least 60%. Otherwise, iron, the chief impurity in tin concentrates can form tin-iron alloys and result in inefficient recovery of tin. Therefore, a hydrometallurgical technology to treat lower grade tin concentrates is proposed to solve the problem and close the demand gap for tin. The electrochemical reduction

The recycling of tin - ScienceDirect

01.01.1987  The solder adhering to the workpiece, however, is recovered if the component is scrapped, generally from the secondary copper refining industry, when the circuit board, telephone or car radiator is smelted. Solder in, for instance, tin cans and car bodies is, in general, not recovered at all.

Secondary Oil Recovery - an overview

Tertiary recovery is started when secondary oil recovery techniques are no longer enough to sustain production, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high, previously unprofitable wells are brought back into production, and when they are low, production is curtailed. Thermally enhanced

What is secondary oil recovery? HowStuffWorks

29.08.2012  There are three main methods of secondary recovery: thermal recovery, gas injection and chemical injection. The most widely used method of secondary oil recovery is gas injection. Once gas, such as nitrogen or carbon dioxide, is introduced into the reservoir, it expands. This expansion forces oil through the formation and into the well. Gas injection accounts for 60 percent of secondary oil ...

Recycling - International Tin Association

The Recycling Input Rate (RIR) is a percentage of the contribution to this total of secondary tin, both in refined and unrefined forms, and in 2018 the RIR of tin was 31%, with re-refined tin contributing approximately 13% and the remainder reused or reformulated alloys. These rates have varied between 30-35% over the last decade, with dips generally corresponding to periods of tin price lows.

Recycling Tin from Electronic Waste: A Problem

Most recycling from waste PCBs has focused on metals like Au, platinum group metals, and Cu, which have high economic value, but tin also makes up a large proportion of the metal in waste PCBs. Over the past decade, ∼44% of the refined tin has been used as solder in the electronics industry each year. Although current global tin reserves can meet the short-term demand, for long-term sustainable

Recovery/Recycling Methods for Metal

A second option is to reuse rinsewater, such as counterflowing an acid pickle rinse into a cleaner rinse. Another method to reduce flow is by flow-control solenoids that are energized by either conductivity sensors or programmed to energize only when parts are in tank. Lastly, pretreated wastewater can be reused in non-critical rinses; this typically requires filtration or microfiltration to remove suspended solids.

Tin processing Britannica

About 80 percent of the world’s tin comes from alluvial or secondary deposits. Most of these occur on land, but in certain areas, notably in Indonesia and Thailand, the deposits are mined offshore by dredging the seabed. Even in the richest tin fields, the concentration of tin is very low. This means that up to seven or eight tons of ore may have to be mined in order to recover one kilogram of cassiterite.

Comprehensive recovery of Sn-Cu bearing

Abstract In the production of tin, much Sn-Cu bearing residue is yielded, and it is an important secondary resource for Sn and Cu recovery but has the disadvantages of a low metal recovery rate and low-concentration SO2 pollution. In this study, alkaline pressure oxidative leaching (APOL) was proposed to dispose of the Sn-Cu bearing residue.
