High-pressure Desorption Electrolysis
This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.
This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1

Ruifeng Optoelectronics announced the 2012 annual report and the 2013 first quarter report: in 2012, the company realized a revenue of 500 million yuan and a net profit of 46.86 million yuan, a year-on-year increase of 71.63 and 41.38 respectively, corresponding to an EPS of 0.44 yuan; in 2013, a Q1 income of 121 million yuan. The growth was 62.62, and the net profit was 8.56 million yuan, an increase of 71.85.
Medium and large size backlights are the main driving force for revenue growth: in 2012 and 2013, Q1 large-size backlight LEDs were the company's first major business, with revenues increasing by 169.31 and 123.37 respectively. The company has become the largest supplier of LED TV backlights in China.
The second largest business LED lighting revenue increased by 15.87 and 34.64 respectively. The price increase of the product decreased, and the gross profit margin decreased greatly: in 2012, the company's LED package component sales increased by 88.81, but due to the maturity of LED product technology and the large capacity production The price of LED components continued to drop sharply. In 2012, the company's gross profit margin was 22.10, down 5 last year. In 2013, Q1 further dropped to 21.80.
In 2013, LED backlighting and lighting business will have high growth of two-wheel drive company: With the further increase of LED TV penetration rate and large-scale TV acceleration, LED backlight demand will continue to maintain high growth, the company will further consolidate its leading position in the domestic industry; The increasingly popular price will be fully rolled out in the commercial market and gradually penetrated into the household sector. The company will strengthen cooperation with international manufacturers and will share the accelerated growth of the LED lighting market.
The EPS for 2013-15 is 0.65/0.83/1.05 yuan. It is estimated that the company will achieve a net profit of 0.71/0.91/115 million yuan in 2013-15, a compound growth of 35 in three years.
